Great experience, simply and easy. Got my stock 5.3 running with a cam in my LS mower. Would reach out to them again.
The tune is amazing and my Yukon runs well
Sent my computer in and received it back promptly. Very easy process.no problems,car runs great with the new cam and new tune,thanks!
Fast turn around works great
great job very responsive. these people know their stuff!!!
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
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.
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.
Everything worked out great as planned Casey explained the new tune. I just now figured out that I need some transmission work lol.
KASPER PERFORMANCE EDGE A.
Casey always gets it done
I just wanna say Casey you're fucking awesome!!! You brought my sierrra back to life!! This truck has 345,000 miles and it still going strong!!! I can't believe it!! You did a fantastic job. Thank you!!!
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
Works pretty well as far as i can tell i would recommend to my friends.
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
Truck runs great!! Quick turnaround time to get me up and running. Very happy!!
Very pleased with your service. Super quick turn around time!
Running for 3 years now! Best tuner out there 6.0 screaming still! Don’t go to anyone else! He’s the best!
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!
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
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.
ECM worked well for the 2015 Silverado 5.3L L83 Gen V DOD delete project.
The tune was what I needed also turn around was fast.
Excellent customer service. Fast shipping and very knowledgeable staff!
They were fast they tuned my truck for a cam I rebuilt motor it started right up with no hesitation and no problems idles good
2001 corvette 6 speed
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 .
After installing my cam truck was undrivable. After these guys tuning my truck it runs amazing!! Beats paying $600 for a dyno
So far so good we’ll see how the tune goes but I’ve heard good things
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!
Casey was fast, professional, and helpful! Thank you MailOrderTuner I will definitely use your service in the future!
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.
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.
It runs. I still need to take it to the track.
Done heads and cam in my 1999 silverado 4.8 and deleted Egr. Mail order tune hooked me up highly recommend.
I was very impressed with how quick I received the Tune file. The customer was very happy with the way his car performed
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!
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.
Great work, extremely helpful. Goes above and beyond.
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.
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.
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.
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.
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.
I love yall work and yall will stand behind it I will continue to do business with yall.
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.
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!!
Tune runs perfect customer service was perfect and turn around time couldn’t have been faster
Thanks so much... I Love It!!
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.
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!
it is great my car sound and feels great, love the tune and will keep doing business with them!
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!
Excellent service. Did a fantastic job fixing a tune someone else messed up. Highly recommended.
