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!!

Truck runs good for what it is, needs more real world tuning to get it perfect but it works.

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.
Donnie W.

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

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!

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!
Antonio R.
Installed the Ecu and it fired right up. Quick delivery also. Would recommend to anyone doing a LS swap.
Brad L.
It runs. I still need to take it to the track.
Chance G.
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!

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
Eric w.
Very fast turnaround and tune is exactly what I wanted . Big thanks to you guys and your great customer service .
Sam Harry
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.
Julie J.
Thanks guys for the great tune and getting my 68 ls1 swap up and running . Highly recomend these guys , top notch. Thanks again!
Neil Schwisow
