Over the top customer service, was my first time using HP tuner and they walk me thru every step to make sure I loaded the tune properly. Can't thank them enough.
Mike C.
Casey has been great to deal with. Fast turnaround.
After just a few tunes the car runs awesome, couldn't be happier highly recommend.
Clay R.
Casey has my Yukon rerunning awesome! I rebuilt the 5.3, did AFM delete & cam. The HP Tuners bundle was just what I needed. The car is running so smooth now, with plenty of power. What’s even more impressive is the transmission tuning. I used to hate the 4l60, but I had no idea they could shift so clean after a tune. Very impressed.
Chris S.
Thank you mail order tuner!! Casey and his team did an amazing job in every aspect of the experience. Casey went above and beyond to make sure my truck had the best possible tune. I would definitely recommend mail order tuner!
Coy C.
Everything worked great once I replaced the bad spark plug wire. My tuner was amazing and so helpful. Would definitely recommend and use again!
Tyler F.
Recently had to change tuners for my LS, after using Mail Order Tuner there’s no going back. These guys are more than willing to help you answer any questions you have, and they got my tune back to me the same day as they received my stock tune. Super fast, and helpful. I recommend them to everyone!
Shane G.
Was very impressed with the tune on my 2012 Vette. Had a few questions and the response time was within minutes. Several great walk thru videos to get everything set up and car tuned. Car feels great and pulls hard.
Marcus G.
I wasnt sure what i needed so i gave Casey a call and after talking with him for a few minutes we decided on the hptuners bundle. He talked me through it and i watched the video on his website and got my truck running great. Casey was awesome to work with and would highly recommend this to anyone who is needing a custom tune. Im excited to work with him again in the future.
Matt R.
Casey was an awesome guy to work with on getting tune done, he dedicated his spare time to help me work through a couple issues, by far the best customer service, will work with him on other projects in the near future
Matt A.
Was very helpful when I had a question very responsive with emails!

Not sure how everything is going to go but they have been great to deal with.

For the first time every having to deal with having to do a tune up for a DOD deletion. A friend recommended your company to me. I'm glad I had you did the delet in the computer. It works great and runs better than it ever did. It was also a fast turnaround as well. Thank you ver much i appreciate it. I would recommended anyone to to all. Again thank you great work
Patrick M.
Casey did an unbelievable job with my 2011 Chevy Avalanche. He did a DOD/AFM delete, also a VVT delete. The truck has never run better. From the first call all the way through putting the ECT back in the truck and post-job questions he was extremely responsive, knowledgeable, and helped make a difficult job much easier. I highly recommend MailOrderTuner, don't waste your time with anyone else.

Once again Mailorder tuners have knocked it out of the park! This is my 2014 100% stock corvette, after their tune it is much more responsive through out the entire power band and even better gas mileage!!
I love these guys!!
Thanks a million

Started right up. Need to replace an 02 sensor though.
Jonah R.
Was considering loading it up and taking my corvette to a local tuner .
It was just so much easier to have it done by Mailorder . I’m sure there are some Hp left on the table but for half the price less headache . It is worth it
Jonathan J.
Casey and Staff (Tamara) helped me plan my 1st LS performance project. I've been a Gen. I SB Chev. guy for decades, so I needed help with the whole ECM/tuning thing.
ECM removal, shipping, turn-around and re-install, couldn't have been easier - or quicker (less than 1 week).
My '99 Silverado 4.8L LS, has only been modified by conversion to a simple, dual exhaust, Brian Tooley Truck Norris, NSR Cam. and Mail Order Tune (MOT - Love it!), ECM tune.
I took my little "Sleeper"/Driver to its 1st car show just a couple weeks after the cam. swap and MOT ECM tune. When I idled in and parked, I was turning heads!
What a great sound and this 4.8L can really push the truck now! Best low budget, LS powered "street car" ever!
Next steps are MOT HP Tuner bundle, better exhaust and 6.0L Block.
I'd only make this kind of investment because I know I have MOT's personal, patient, customer care and tech. assistance one quick phone call or email away.

CHRISTOPHER M.
great job very responsive. these people know their stuff!!!
Michael D.
ECM arrived Had reduced power. Would only rev 2 grand. Thought it was the rev limiter. Casey said it was something mechanical and would program my my stats on his end to prove it. At this point I just about gave up. Turned out to be the brand new throttle body I put on. I know huh? Bunk. Put on the original, and in one start I knew I had something. No lights, nothing. She runs like a dynamo! This company is the real deal, and they know what their talking bout. My truck runs better than expected, and has power to reserve. Thanks from my end. Mike
Isaias G.
I installed TS CHOPacabra CAM from TSP in my 2005 Hummer H2 with only 58,788 miles on it. I sent out my ECU to Mail-order tuner for a street tune since here in California, no one has the all-wheel drive Dynos, at least here in Southern California. Anyway, I got it back within a week and yesterday I finished the cam swap turned on the Hummer H2 and it sounds amazing! The tune was awesome, almost if I had taken it to get dyno tuned. No Check engine light on. I did however, had a slight RPM variation but drove it all day today and it went away. The Truck sounds amazing, and the tune was even better. I would definitely, recommend this place for a mail order street tune. Thank you, guys.
Kendrick W.
Good business

Filled out online form, and left a more descriptive note of engine and part specs in the box, he called me at lunch to double check and verify a couple things and I had the computer back the next day. Truck fired right up, I’m ready to drive it.

Almost one year to the day from when I ordered my tune, I turned the key for the first time and my motor immediately roared to life. This thing is great. I would highly recommend Mail Order Tuner for all your tuning needs!

Great experience from start to finish couldn’t ask for anything better thank you mail order tuners
Cole K.
Works pretty well as far as i can tell i would recommend to my friends.
Marcus G.
Casey is awesome to work with. Quick turn around time on tunes and he knows what he’s doing. He did my initial tune once I did my ls swap. After a year I called him and asked for cam recommendations, bought the cam and everything to go with it including a retune from him. Has been very helpful and awesome to work with. Would definitely recommend
Duane K.
Truck runs great!! Quick turnaround time to get me up and running. Very happy!!

Did a great job solving a idle/stalling issue on my ls7 427 crate motor. Engine has a pretty radical cam that had no manners at idle. Sent the pcm to MailOrderTune and they turned it around very quickly and worked perfectly once installed. Thank You for the very competent service!
Greg B.
Casey went above and beyond this is the second tune i have gotten from him and as always never disappoints. We Have a fleet of these suburbans and have done various AFM deletes and 6.0 swaps and he always gets the tunes just right. Will definitely be using him for all our tuning needs
Caden I.
Casey has went above and beyond for me. 10/10 will always go back to him. I put a stage 2 BTR truck cam in my wife's 5.3 silverado. I thought I would be able to tune it myself, but boy was i wrong ha. I had a couple things wrong on my end, ( mechanically.) Casey was patient with me, tried to help me through the issues, gave me a few phone calls. Truck is running a million times better thanks to him. I really appreciate all the work he has put into the truck and helping me. He responds very quickly, he's on top of it for sure! He gave me recommendations on good set ups. If you need tuning/help you're definitely in the right spot! So, thanks Casey I appreciate everything you've done, 10/10 will be back.

I needed a new motor in my truck and I had a gen 3 6.0 sitting around. I built it to replace a gen 4 5.3. These guys were able to program everything I needed for the swap. Dropped it in and it fired right up and runs great!! I had some questions after I had it running and their customer service is top notch. I would highly recommend them for your next build!!

These guys are awesome. After a cam, stall and a bunch of other goodies I sent my pcm to them. It’s back and in the truck it idles great and pulls like a freight train. They have to know what they are doing especially when you consider weren’t with the vehicle and did all this from Texas. If your not getting a dyno tune, this is as good as it gets in my eyes.
Jon B.
ECM worked well for the 2015 Silverado 5.3L L83 Gen V DOD delete project.

Basically stock car that I drive daily to work.
I decided to put a Texas speed low lift max cam to wake it up a bit.
The mail order tune really just made the whole install painless,
No loading it up and traveling 4 hours to get it tuned.
It runs amazing with a great choppy idle .
I was the Ginny pig for a couple guys that have also wondered about mail order tunes.
They are sold .
Thanks again
Brandon d.
After installing my cam truck was undrivable. After these guys tuning my truck it runs amazing!! Beats paying $600 for a dyno
Austin D.
So far so good we’ll see how the tune goes but I’ve heard good things
Jake P.
Casey did an amazing job tuning my car after installing a cam, stall converter, and a built transmission. Idle is great and the car pulls good as well. Would definitely do business again!
Cassie G.
Casey was fast, professional, and helpful! Thank you MailOrderTuner I will definitely use your service in the future!
Jason M.
Casey solved the problems I was having with my tune for the past however many months in just 2 hours. I would highly recommend this service to anyone who is looking or considering a tune. The tune was better than the local dyno tune I received at half the price. Still amazed at how quickly this man can do this, wish I had gone through him from the start, and I will likely continue to use his services in the future.
Alexander H.
Sent my pcm off on a saturday and got it back the next thursday. Finished engine install and car started right up. No CEL, no idle issues. Thanks again!

Installed the Ecu and it fired right up. Quick delivery also. Would recommend to anyone doing a LS swap.

Done heads and cam in my 1999 silverado 4.8 and deleted Egr. Mail order tune hooked me up highly recommend.
Danny N.
I was very impressed with how quick I received the Tune file. The customer was very happy with the way his car performed
Ricky R.
What s great service! I tried everything to get my truck to run like I wanted it to, with the power I wanted. Sending my computer in was super easy and turn around time was so fast! Easy to fill out paperwork, easy instructions for sending the computer to MailOrderTune and they sent it back in just a couple of days. Truck sounds GREAT and runs just like I wanted. I definitely recommend these guys to anyone!
Mark M.
Called before I jumped. Compared timing and coat to local tuners. Mail Order Tuner was 1/2 the cost and twice as fast as my local tuners. Truck fired up first time and runs great. Rebuilt my 2012 with dod delete, vvt delete, stage two tsp cam and summit racing headers.
Carl G.
Great work, extremely helpful. Goes above and beyond.
WES S.
Made a 68 Camaro with a 6.0 Ls run great. Really woke up the performance cam and runs even better than expected. Great service.
Michael G.
Fast response and turn around time. 6.0 Lq4 and 4l80e swap into my 82 Chevy K20. Once I finished all my wiring, first turn of the key and it fired up. Great service.
Travis P.
New cam install went a lot more perfect with MailOrderTune, I sent it out a day before I started the cam swap, got it back a few days later. Car started right up with no CEL, idled, and drove fantastic. Its a great way to get up and running properly if you don't have immediate access to a dyno tune place.
Cherastina W.
Greatest experience ever. First time doing this and they made it so effortless. If you're looking to do business with them I wouldn't hesitate.
Joe B.
Got a cam for my 2000 GMC 5.3 from TSP and I thought the truck ran okay..until I had the folks at MailOrderTune tweak it, truck runs better then I thought it ever would. Very happy with the service and turnaround.
Jerome T.
I love yall work and yall will stand behind it I will continue to do business with yall.
Dalton T.
The customer service is amazing. After my cam swap i sent the pcm to them they tuned it the same day they recieved it and i had it back the next day. The power i gain is amazing and the truck drives and idles fine considering it doesnt have a converter yet.
Thanks guys.
Anthony H.
Mail order tune was spot on in my 2002 C5 Z06 with TSP headers and TSP 233/239 112 LSA cam. Car idles perfect and sounds mean! Makes awesome power!! Super fast shipping and communicates very well!! Thank you guys very much!!
Karl G.
Tune runs perfect customer service was perfect and turn around time couldn’t have been faster
Michael L.
Thanks so much... I Love It!!
Bill
These guys know their chit! Great to work with. Sent it in and had it back in like four days total time. We had a couple of unforseen changes in our build and they're retuning it for free. Most of my "hot rodding" dealt with carbs and no electronics past a tricked MSD setup so this stuff is new to me. They are the best help I could've found! I will be a repeat customer for other projects.
Clay Y.
Just did a simple cam swap on my truck nothing else really except some basic boring bolt ons and got it tuned by Casey and the truck runs perfect. The trans was on its way out prior to the swap so thats the next project but great guys, they know what they’re doing. My ecu got there at 8:50am and they had it tuned and shipped back out to me by 12 that afternoon. So basically a 3 hr turn around, you can’t beat that!
raul c.
it is great my car sound and feels great, love the tune and will keep doing business with them!
Jose
Excellent service, called about my setup and Brad took his time explaining options. The tune provided by Casey is perfect

Very fast turnaround and tune is exactly what I wanted . Big thanks to you guys and your great customer service .

Shipped on Saturday, got it back on Tuesday. My Suburban has never run as good. I get better fuel mileage now even though I removed the Displacement on Demand. This is one of the few places that knows how to tune a truck. I’ll be sending in my Silverado soon.

Thanks guys for the great tune and getting my 68 ls1 swap up and running . Highly recomend these guys , top notch. Thanks again!

This has to be the most reasonably priced and honest tuner around. Turn around time is very speedy. This my second time because mechanical issues I was having. Casey saw it in the tune!!!! I swapped my heads out sent in the info and had my tune at like 9:08 the next day and they open at 9. That's just dedication!!!
Derrick C.
Casey at mailordertuners.com has the E-tunes streamlined very easy to work with. The tech page on their website has all the info on how to data log, install tunes, read and write files etc. His response time on receiving your data logs and adjusting your tune is top notch within the day you send your data logs you'll receive your tune if not multiple in the same day. The tunes he does are quality he'll keep working with you until the tune is 100%. I have nothing but good thing's to say abt mailordertuners.com.

Highly recommended company very fast response very knowledgeable good solid Tunes
Jason M.
Great customer service! I had a GMPP E67 ECU that came with my crate LS376/525 engine. It wouldn't stay running until I had it retuned. In 2 tries they had it running like a top. I had my 2nd revision withing 24 hours of the order and it was on a Saturday. I wasn't expecting that at all. I wouldn't go through anyone else for tuning.
Chris T.
Casey tuned a low mile built 2002 Collector Edition Trans Am WS6 for me in 2018 and it performed great right up until we sold it recently (2023). He also just tuned out 3800 mile Tom Henry Racing GMMG SS Camaro Phase 2. It sounds the best it has since we've owned it and performs great. Great work and a quick turn around (24-48 hours). I've referred several friends and they've all had a great experience with him also.

Casey's tune was great right from the start. fired right up, idles great, and pulls hard. im sure it will be even better with a re-tune but im very impressed so far. He was very up front with his opinion on my power/rpm goals vs parts i was using, and gave me solid recommendations. Which I followed.
Erwin P.
I followed the instructions on what to send as far as current tune and log upon initial start up, when I received the tune back it was on point!!!

Really a great job start to finish. Ls1 with cam and intake and fired off first crank and runs great. Strongly recommend and will use again
Albert A.
Very professional and understanding tech that took care of my tuning needs. I installed and LS3 hot cam motor in my 63 Nova SS. It took a couple of extra steps to get it done because Casey, the tech, explained that LS3's came with either one of two versions of the MAF and it was initially set up for the other version. Once that was done, the rest happened quickly. I am working on another project, which I told him about, and he will get that job too. Thanks!!
James R.
Very impressed with the customer service, turnaround time, and of course the tune! This is the second vehicle I have worked with them on, and definitely plan to use them more in the future.

Great company to deal with I somehow sent them a file that I couldn’t load back into my rig and they helped me out got it all squared away and redid it and didn’t charge me a dime to do very good people will use them again A+ company thanks you
Byron C.
I am extremely happy! I swapped a 2014 l83 into a jeep w/stage 2 cam ported heads corvette intake and throttle body and numerous other odds and ends. Casey has been awesome helping me get it running and driving perfect. The response time and turnaround time are second to none even on the weekend which blew me away. The process is super easy and well worth every penny. I will definitely be using them for all my tuning needs and future builds and will 100% recommend them to everyone!
Josef B.
Casey has been amazing! He's helped get my 58 Biscayne up and running beautifully! Very knowledgeable and wouldn't take my tune anywhere else!
*# D.
Nice to deal with a professional operation that responds properly and made the adjustments quickly.
Matt G.
KC and the mailordertuner staff was great to deal with. The tune my car had when bought was a disaster. This was my first go with email tuning and HP tuners. They made the process simple, painless, and enjoyable. All updates were sent super quick, even on weekends. I can't recommend enough.
Tyler H.
Very straight forward and easy quick programming
Jeffrey H.
100% would recommend my truck gets around 23mpg on highway with a stage 1 tsp cam..... also very fast response ⭐️⭐️⭐️⭐️⭐️
ryan l.
I am beyond impressed the process was easy and the outcome is great.
Aaron W.
Got the new LS1 tuned up and ready to rip in no time.
SCOTT P.
I can't say enough good things about this company! They care, they are prompt, they are easy to deal with.... You don't just send them your log and get a tune that "should work" like other companies do. They work with you getting updated logs for each step and get it dialed in properly! I would recommend to anyone. The car runs great and really flies!
Brad C.
Super happy with this tuning service. Exceeded my expectations and were very helpful. Sent my engine build list and got a start up tune within a few hours. I ran 1 data log and and basically had it dialed. I had a small hick up a week later and no problem getting sorted out. Even over the Easter weekend. Would definitely recommend.

Casey and his team at MailOrderTuner provide the best remote tuning services BAR NONE! The process of providing specs of your build, uploading a current tune file, and receiving a tune that can plug in to run your build is priceless! If there are any concerns, Casey is quick to assist in the best way he can because we are remote. I will be sure to use them for my future needs! Don’t hesitate to use this service!
Justin P.
Installed TSP stage 2 cam and with no tuners near me Mail Order Tuner was recommended by Texas Speed and Performance glad I listened to them. Fast turn around truck runs great. Will definitely be using Mail Order Tuner for all of my tuning.
David H.
My Dyno tuner was a 100+ miles away, so I needed a way to get the car there (without trailering). Got the mail order tune in the car and it ran great !!! I was able to put a lot more break in miles on it than I had anticipated. Got the Dyno tune, and I’m not sure there was much difference, I think it was pretty close already :-) Thanks!
Charles H.
Everything going with the truck having some small issues. would love for Casey or staff to contact me at 469891503
Luther A.
Great experience! I did a heads, cam, headers, vvt delete, afm delete to my 2013 Camaro SS. I downloaded the tune with HP Tuners, mailed it to them and got it back the next day. Flashed the tune, data logged the car and sent it back. They were even cool enough to call me to answer some questions. I would absolutely use this service again.
Douglas M.
Great customer service! I wasn’t happy with my first cam. (It was recommended by someone else) I talked to Casey told him what I wanted to do with the car, and his recommendation nailed it! I highly recommend his knowledge and tuning abilities if you are going to do a cam, call and get a all of the information you need before you waste money on something that will not make you happy.
Josh T.
It was all very easy and they pretty much walk you through step by step on how to do it.

I’m in love with my truck all over again!! Had a lifter failure and chewed my TSP Stage 3 cam up on my L83. So I installed all new needed parts plus TSP BFD chop monster cam and with this tune my truck has never sounded nor ran this good! Thank you for giving me more than I was ready for!!

I recently moved to Vegas didn’t know anyone when I did my motor swap went to 3 shops to tune my truck spent good money and all 3 couldn’t get the truck to run right , every one of them had excuses why it couldn’t ( cam was too big, not enough vacuum, fuel system etc). With Mail order tune I sent my old tune with a list of my upgrades and within 48hrs I got my new tune back flashed my pcm with hp tuners and truck has never ran so good. First test run I was so happy I just wanted to see how long of a black mark I could make on the road hahaha I’d say stop your searching and let these brother tune your sh!t. Thanks again for the tune guys
Rosendo R.

I have heard fantastic things about MailOrder Tuner and Casey’s ability to tune GM LS engines, I did a DOD delete on a customers Avalanche and installed a custom cam valve springs and other minor parts. He introduced me to HP Tuners MVPI2 and guided me through the process of writing and reading tune files, within a few tunes he had this machine running and pulling crazy hard like a complete new truck better than can be imagined. I Couldn’t imagine how the proper adjustments and knowledge to do so could make this engine perform. I would highly recommend anyone that’s looking for a computer tune to have Casey performer his magic for you. It’s worth it’s weight in gold.
Thanks very much for an excellent job. Dave Punkari

Hands down best customer service in the business!! Casey has no problems at all to take the time to make sure it's right. They have gained a loyal customer!
Dan F.
Installed a TSP stage 2 cam, headers, and cat delete in a 2010 camaro. Sent my info in late Friday afternoon and got the tune back that evening. Car started right up, no check engine lights, and more importantly runs awesome! Extremely satisfied.
Jeremy C.
Working with Casey has been awesome! Super knowledgeable and made it easy with the revisions on my LS tune. By the third tweak, its running about as good as it can get. You can definitely tell that he's been around these engines a long time and he knows which tables effect certain parameters of the characteristics of the run. Thanks again for getting her running and sounding amazing!
Brandon .
very fast and knowledgeable will definitely use again
Garrett C.

Tuners was just what I needed to get my build rolling
Justin M.
I installed a summit stage 2 cam in my 2003 4.8 Silverado and needed a tune. My ECM made it to Texas on a Wednesday morning and Casey called me to go over a few things about my truck and they shipped my computer that evening. I got it a couple days later and installed it in my truck. It fired right up and runs awesome! Sounds like a racecar just like Casey said it would!
Brandon B.
Sent in my ECU to mail order tuner and had them tune it and they had a very fast turn around. Got it back in and it drives awesome! And no more check engine light for the O2’s!
Matthew C.
Needed a custom tune to get my 1997 k1500 with a gen 3 5.3 ls swap up and running and the crew at mail order tuner did not dissapoint. My computer was retuned and on its way back to me the same day it arrived and they even called me with a couple questions to make sure everything was done right the first time. Great company would highly recommend for all tuning needs
Raymond S.
Excellent service, fast turnaround, works perfectly
juan r.
Great services externally fast turn around time. The only thing would be the need to up their packaging. I know it's the mail carriers fault but 1 bubble wrap envelope would protect my ECU from damage. It still works but it's damaged now.
Frank N.
Runs like a champ
Tanner D.
I have a 2005 GMC Canyon with an LS 6 L swapped in it with a truck noise cam the tune quality is very well very fast turnaround truck runs very well would highly recommend
tim t.
Great service. I mad a user error and they offered to help under warranty just costing me shipping which I’m very thankful for. Good service and great product in regards to tuning success.
Blake L.
The team over at Mail Order Tuner’s has the best customer service, hands-down. They have gone back-and-forth with me trying to get the motor tuned in my truck after we swapped a bunch of parts and a computer. Casey stuck with us the whole way. In the end result was an amazing running truck with an excellent tune. Highly recommend them for anything LS, they will be the only ones tooting my truck for as long as I own it!!!!!!
Michael M.
What more can I say that has not been already said!!! Unfortunately I can only give 5 stars, WISH I COULD GIVE MORE!!! I've been to 5 other tuners, NOT 1 tune has performed better than MAIL ORDER TUNER!!! THANK YOU Casey and the MAIL ORDER TUNER family for their KNOWLEDGE and EXPERIENCE!!! I WILL NOT TAKE MY 2015 CAMARO SS 1LE LS3 416 STROKER ANYWHERE ELSE FOR MY TUNES!!! THANK YOU, MICHAEL
Matthew M.
One of the best LS tuners, very helpful and knows what he’s doing
Tyler S.
I’ve done a few retunes so far on my 01 Tahoe and I’ve loved it all. From fbo to cam and heads, I’m truly grateful to Casey and the team for their patience and help with my NA build this past year as well as all that is yet to come.
Josef B.

Over the top customer service, was my first time using HP tuner and they walk me thru every step to make sure I loaded the tune properly. Can't thank them enough.
Mike C.
Casey has been great to deal with. Fast turnaround.
After just a few tunes the car runs awesome, couldn't be happier highly recommend.
Clay R.
Casey has my Yukon rerunning awesome! I rebuilt the 5.3, did AFM delete & cam. The HP Tuners bundle was just what I needed. The car is running so smooth now, with plenty of power. What’s even more impressive is the transmission tuning. I used to hate the 4l60, but I had no idea they could shift so clean after a tune. Very impressed.
Chris S.
Thank you mail order tuner!! Casey and his team did an amazing job in every aspect of the experience. Casey went above and beyond to make sure my truck had the best possible tune. I would definitely recommend mail order tuner!
Coy C.
Everything worked great once I replaced the bad spark plug wire. My tuner was amazing and so helpful. Would definitely recommend and use again!
Tyler F.
Recently had to change tuners for my LS, after using Mail Order Tuner there’s no going back. These guys are more than willing to help you answer any questions you have, and they got my tune back to me the same day as they received my stock tune. Super fast, and helpful. I recommend them to everyone!
Shane G.
Was very impressed with the tune on my 2012 Vette. Had a few questions and the response time was within minutes. Several great walk thru videos to get everything set up and car tuned. Car feels great and pulls hard.
Marcus G.
I wasnt sure what i needed so i gave Casey a call and after talking with him for a few minutes we decided on the hptuners bundle. He talked me through it and i watched the video on his website and got my truck running great. Casey was awesome to work with and would highly recommend this to anyone who is needing a custom tune. Im excited to work with him again in the future.
Matt R.
Casey was an awesome guy to work with on getting tune done, he dedicated his spare time to help me work through a couple issues, by far the best customer service, will work with him on other projects in the near future
Matt A.
Was very helpful when I had a question very responsive with emails!
Jeb B.
Not sure how everything is going to go but they have been great to deal with.
