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!

This is the second time I’ve worked on getting my truck tuned with Casey and let me tell ya I got zero complaints. extremely easy to work with and will walk you through your first time. 1st tune was for a cam then a retune for a high stall converter. I always get a response next day after every log or base tune! He’s got the truck dialed right in and it’s a beast. I would never switch tuners and I would highly recommend to anyone that reads this to let this be your sign to use Casey as your tune...

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!

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.

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!!

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!!

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.

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 . Thanks again

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...

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!

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 variat...

Casey did a really great job on the tune. My car feels more responsive and rides and shifts much better than what I had before (previous tuner only 421WHP and 378WTQ with the VVT3.2 CAM). I truly can feel the difference, not to many people can tune the car correctly with VVT. If a tuner tells you to delete the VVT system in the car most likely they have problems tuning VVT systems. Have an expert like Casey do the tuning remote tuning. You will like it.

Tyler R.

Casey is top notch. Sent my computer on Monday and had it back in the car by Friday. Literally tuned and shipped back out the day he got it. He even called me on some things that were listed in my build sheet and advised me on what he knew would work better. He has zero dollars invested in my car and was still concerned with making sure everything was safe. I've probably reached beyond PITA level but he never once veered away from answering any questions I had. I will gladly let him advise and t...

I’ve been driving this for about a week after the tune was installed. I am so impressed with it, it’s like I’m driving a totally different car. It totally changed the performance and sound of the car. And it unlocks what the LS2 has to offer. Also helped me with e check. 😁 thank you mail order tuner!!

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 quick...

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

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. 2003 Silverado 1500HD 4x4 LQ4 6.0L 706 heads Summit stage 1 high lift cam, TBSS intake.

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 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

Did a lot of research on email tunes and who was the best. I saw he tunes for Texas speed and knew I would be in good hands. I wanted to build a sleeper and it is just that. I originally got a tune for just a cam. I put a turbo on and he got that dialed in pretty fast. I had a couple of problems on my end. He instantly had an answer to everything and told me how to fix it. My truck runs great and I wouldn’t trust anybody else tune it! TSP stage 3 turbo cam kit, trunion upgrade, 80lb injectors, ...
