My tune came back spot on! It's exactly what my truck needed! The turn around time on the ECM was really quick, and I was contacted right away to make sure everything was good. I highly recommend MailOrder Tuner!

My experience went exactly as advertised. I installed a new cam in my Camaro ss LS3 and needed tune. I got emailed the new tune very quickly after sending my stock tune. I think in total I had 4 or 5 "re-tunes" where I sent a datalog after downloading the new modified tune. It took me about a week in a half in total from start to finish, but that was only cuz I was limited in the times I could take it for a drive to datalog. It probably could have been done in half that time or less. Camaro run...

I love this service email your computer off you don't have to bring it into a shop emails it back to you faster than you can have a cam put in very responsive and knowledgeable and the prices awesome people were paying up to $1,000 to have it tuned at a shop and only paid $450 with Casey

This has to be the most reasonably priced and honest tuner around. Turn around time is very speedy. This my second time because mechanical issues I was having. Casey saw it in the tune!!!! I swapped my heads out sent in the info and had my tune at like 9:08 the next day and they open at 9. That's just dedication!!!

These guys are AMAZING. It was so easy to and the results are great. They really know what they are doing. We had a “stage 1” BTR cam and dod delete done on a 2015 5.3. It had a random misfire for about a year and after chasing everything else down, per a local shops recommendations, we decided to delete. I was very surprised with the power gain and how smooth my truck runs now. Thanks so much. Highly recommended.

Had my truck tuned locally but just didn’t run as expected. Overnighted ecm to mailordertuner.com with my build info. 3 days later had it back & installed. Incredible difference. Truck runs awesome. Will use them for all my tuning going forward. Thanks!!

Ended up having to pull the engine back out and have it bored .020 over and swapped the std BTR pistons with WEISCO Pistons .020. over. Can you make the adjustments to the tune file as we will be reinstalling the engine within the next couple days. We will definitely add pics and video along with the data logs after the engine break in. Thanks

So far the gentlemen have been great getting my tune dialed in. They have made every effort to get my truck running right, and I believe they will make it happen. I will give update once it’s all dialed in.

I wasnt sure what i needed so i gave Casey a call and after talking with him for a few minutes we decided on the hptuners bundle. He talked me through it and i watched the video on his website and got my truck running great. Casey was awesome to work with and would highly recommend this to anyone who is needing a custom tune. Im excited to work with him again in the future.

Was scared to send it at first but the guys at mail tuner made it so easy. Shipping was perfect. And they are super fast. Will be using them for my shop again in the future.

Always a quick response. And when they're is something not right they let you know. I've dealt with other tuners who will try and mask mechanical issues. Casey let's you know when something isn't right.

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.

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.

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.

Casey's tune was great right from the start. fired right up, idles great, and pulls hard. im sure it will be even better with a re-tune but im very impressed so far. He was very up front with his opinion on my power/rpm goals vs parts i was using, and gave me solid recommendations. Which I followed.

Purchased the tsp headers and off road y pipe. Love the sound but it’s way louder than I thought it would be. Should have went with the catted y pipe. Not sure how much it would quiet it down but anything would help.
