I could not have had a better experience with having my Truck's ECU reprogramed to delete the AFM program and work with installed delete kit. The folks at MailOrder Turners are awesome. One day turn around, WOW. When I thought I had a problem with turner when reinstalled, I called Casey, we discussed issue, he said send it back. He checked it out, no issues and even sent video of ECU running on a truck at the shop.
Highly Recommend MailOrderTuners!
Alan F.
Worked!
Xavier C.
All work out fine . Thanks
nick k.
Very fast turnaround. Great communication.
Matthew O.
Such great customer service! 10/10 would highly recommend to anyone!
Bryan G.
Did a ls swap in a 1988 s10 blazer. Not done with it yet, but it starts right up and idles takes throttle .. So far so good...
Dan R.
I dropped my PCM off at the UPS store on a Thursday at 3:00 thinking It would be awhile before I got it back. It arrived back on my porch less than 48 hours later. It took me some time to get the engine ready, but I installed the PCM today and my brand new engine fired instantly, settled to an idle and drove down the street. No drama, no check engine lights, and runs like it should. I haven't driven the truck much yet, but so far I'm very happy with the service. Thanks
Devin M.
Took care of the check engine light and gets better fuel mileage already!
Brandon W.
Runs great and sounds amazing. The crew at mail order tuners are amazing people and get you what you need and want. I had some small hiccups on my end and they still called me back to help me figure out what I needed to do. When I’m ready for more power I will definitely be contacting them back. And recommend every one I know to use them for there set up.
Oliver M.
Quick
Heinrich T.
Truck fired up as soon as fuel rails filled up. Truck runs and idles great. Transmission shifts perfectly. However my rear o2 sensors are still reading even though they were supposed to be deleted for long tube headers which now causes a check engine light.
Lance B.
Great work!my car ran like Sh** after a cam install got my computer in the mail and now it runs about as good as stock with a good chop !
Travis N.

This was the absolute easiest and cost effective option to tune my 04 Suburban that I engine swapped with a BTR stg2 truck cam. Had a couple little issues on my end of things when it was reinstalled, but MOT was promptly there to help out to get it running properly. Couldn’t be happier with the end result though!
Christopher B.
Super easy didn’t do much besides explain the work I had done to it. The Tuner got it done within a hour or so of my computer being there and was back in my car the next day. Car runs super good havnt had any issues and don’t foresee any in the future. Will be using Casey for all future tunes as he clearly knows what he’s doing. Thank you Guys!!

Super quick and easy to get this done. The lady on the phone i spoke with is super kind and very smart when it comes to tuning. I think you guys could also bump up pricing a bit. I felt that this was incredibly cheap and easy compared to everything else on the market. Great job and keep it up!
Thanks
Nick B.
Swapped a 1956 GMC truck body onto a 2005 AWD Escalade chassis. These ECU was for the cammed 5.3 LS I installed. These guys are so fast and so good at what they do. I mailed my ECU out Monday AM and had it back that Wednesday afternoon. No idea how they are so fast!!

Customer service has been great! A real life human with technical knowledge answers the phone! I spoke with Casey and one other rep prior to ordering and they provided valuable information while I was deciding on which DOD delete parts to order from Texas Speed for my 2014 L83. I live in Alaska with limited access to parts and services so I needed to get this right. MailOrderTuner had my ecm back to me in a week.
Josh G.
Casey was phenomenal… extremely knowledgeable and gave me solid advice. I am extremely satisfied with the tune! My 2011 Silverado is running great.

The tuner's team and customer service is top notch, they will speak with you on the phone personally providing answers for any questions you may have. They will also give you tuning recommendations on what may work best for your application. I will keep using this service for all of my tuning needs.
Robert W.
This was my first tune and I was not sure what to expect...Casey was awesome to work with and walked me through the process! He helped me understand important aspects of a tune and advised on the parameters for achieving my performance goals...have lots of plans for my C5 Yellowjacket and I guarantee that Mailorder Tuner will be a big part of those plans!!!

I was very surprised with the power gain and how smooth my truck runs now. Thanks so much. Highly recommended.

Joe H.
In my 2015 yukon Denali XL 6.2 lt1 I did a Texas speed stage one Dod delete cam , with valve springs and Che rocker trunion upgrade.
I was worried about tuning issues but everything mail order tune did was great and exactly as explained .
I called and spoke to someone about my concerns then I Filled out the form and shipped out the ecm. It came back 1 week later ( my shipping, the tune and shipping back to me).
I plugged it in and started up the truck. Runs great. Performs well and all monitors set .
Exactly what I was looking for when doing this upgrade
Charles k.

DOD delete done on my 18 GMC Sierra. Texas Speed referred me to mail order tune. They didn’t disappoint. Super fast. Sent my ECM out, had it back the next day. Zero issues with the tune. Definitely recommend and no question I’d use them again!

In my 2015 yukon Denali XL 6.2 lt1 I did a Texas speed stage one Dod delete cam , with valve springs and Che rocker trunion upgrade.
I was worried about tuning issues but everything mail order tune did was great and exactly as explained .
I called and spoke to someone about my concerns then I Filled out the form and shipped out the ecm. It came back 1 week later ( my shipping, the tune and shipping back to me).
I plugged it in and started up the truck. Runs great. Performs well and all monitors set .
Exactly what I was looking for when doing this upgrade
