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
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!!
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.

Casey never disappoints
Ordered my tune on a Tuesday night. The next morning it was available
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
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!
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!
Nice to deal with a professional operation that responds properly and made the adjustments quickly.
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.
Very straight forward and easy quick programming
100% would recommend my truck gets around 23mpg on highway with a stage 1 tsp cam..... also very fast response ⭐️⭐️⭐️⭐️⭐️
I am beyond impressed the process was easy and the outcome is great.
Got the new LS1 tuned up and ready to rip in no time.
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!
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!
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.
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!
Everything going with the truck having some small issues. would love for Casey or staff to contact me at 469891503
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.
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.
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!!
Very pleased, the tune worked great from the start for my LS swap with a cam! Thanks!
Best price!! Excellent customer service. Love the quick turn around. Will be using them in the future. I will recommend MailOrderTuner to everyone.
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
Great service, very fast turn around. My C6 is running better than ever.
First tune worked great to start was very fast at getting back with touch ups. Will be using again!
i swapped a 5.3 LS out for a 6.0 LS 706 heads for 10.5 -1 compression ported heads BTR cam 202 int 202 exh lift.511 int .511 exh lobe sep 111+1 new rockers put my mail order tunes in it started right up and runs great great , torque from idle to over 5,000use this is for towing 6,000 lb could not be happier
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
Thanks Mailordertune you guys are amazing, this is my second vehicle tuned by you and I am 100% satisfied.
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!
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.
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!
very fast and knowledgeable will definitely use again
Did a dod delete and a cam swap. Got the tune loaded up car runs pretty good even held my own against a zl1 so I'm happy with it lol
Looking for more options with this
Sent tune information in and everything was changed to perfection with great service afterwards
Very impressed with the tune I had casey do on my camaro did a awesome job turn around same day and for being a big cam ms4 no issues will be doing business with him again thanks again!!!!!!!!!!!!!!!
