Customer photo review of Mail Order Tune

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!!! Thanks for all the help!!! it runs amazing!!! Sincerely Spyderwebb

Casey has tuned my built Escalde and now my supercharged Corvette and I couldn't be happier. The turn around from sending in a data file and then getting the tune has always been very fast. I first did an N/A exhaust only tune and the car was very fast and drove so much better than stock and then I did a supercharger and the tune is fantastic. If you're not privy to HP Tuners, watch his videos on their website.

Mason B.

2019 Yukon Denali L86/10 speed Used mailordertuner for my truck and man he killed it. I paid a local guy $700 to tune my truck in person and he could never get it right. Felt down on power pretty much everywhere and the transmission was not happy at all. It took me awhile to finally bite the bullet but I bought his email tuning service as I'm already sorta familiar with hptuners and have my own MPVI3. After the first base tune it was already pretty close. Sent him three data logs total and he se...

I had a hodgepodge of a combination. And they got me running great. The tunes came in as fast as I could send them a data log. The only thing I would ask from them is let the customer know that your retunes are coming to an end. What would you like to see. I will be using them again. 100% satisfied

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!

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!

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.

Dave P.

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 s...

After 3 different tuners, $3000, 1 year and now a 2nd tranny needs replaced, the tuners in my area couldn't tune it right. I used mail order tuner. Casey nailed it the first time. My engine and trans tune was so bad he had to reset my ecu and start over. I highly recommend them. Casey and Tamara were extremely patient and walked me thru the download of my tune, as I have little experience with a laptop but I could work a smart phone really well though,lol. I am so happy, it runs and drives and ...

Raymond T.

To tell the truth, I'm pretty disappointed with my MAILORDER TUNERS experience... Because I should have done it much sooner ! My little sleeper of a truck is fully awake now..... I always liked how it performed. With just a few power adders she was running pretty strong. But I never would have guessed how much more she had to give...... now that I let the tune masters @ MAILORDER TUNERS do their magic........ Holy Hell Ya!! Those gurus are BOSS ! They got my tune on point and crazy as it seems ...

84' C20 Ls swap. GEN 4 5.3 LS with summit 8719 cam, 6l80e transmission. Truck wouldn't run after start up and kept dying due to using LS7 MAF sensor on my set up. Casey got it running after the second log run and after he fine tuned it. He is very professional and a true tuner that I've ever worked with. Truck runs smooth and pulls hard, I love it. Will definitely be doing more business with future swap i be doing.

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!

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!

67 GMC, 05 GTO LS2/4L60E, BTR Truck Norris I was initially very hesitant about going with a mail-order tune, but they came highly recommended—and working with Casey at MOT completely exceeded my expectations. As a first-time remote tuning customer, I couldn’t have asked for better service or a smoother experience. I placed my order Tuesday night and had my final tune by Friday evening, despite a delay on Thursday due to weather preventing me from logging. The turnaround time was impressive. To...

So happy with their service. I'm a hybrid guy. i'm comfortable with jets and springs as i am with computers. I bought the HP Tuners suite and used youtube and some online stuff and had success. until i didn't. I got to a poijnt where every change I made made problems. I found these guys and sure enough they smoothed out my drivebility and confirmed (most importantly for me) that what I saw for WOT was legit. A completed tune for the cost of two tires? Priceless. Please use these guys. T...

110% recommend Casey to get your LS powered project dialed in!! First time doing a remote tuning process and very happy with the results and fast turnaround. Had a small issue with my o2 sensors that was diagnosed very quick. No greater feeling then that first drive after a multi year project hearing a cammed LS scream!

Douglas M.

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.

Great customer service! I had a GMPP E67 ECU that came with my crate LS376/525 engine. It wouldn't stay running until I had it retuned. In 2 tries they had it running like a top. I had my 2nd revision withing 24 hours of the order and it was on a Saturday. I wasn't expecting that at all. I wouldn't go through anyone else for tuning.

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.

This last tune was a straight forward tune up for a customer from Casey for a silverado. Turned out amazing as always. We have used Casey in the past for a few other cars, including our personal vetts. Its been almost 2 years now and he nailed it! These 2 cars get driven hard every single time they fire up and have not had 1 single issue! White vett motor was rebuilt with a massive cam and Casey nailed it even on first start up. Black vett was retuned from him and easily picked up another 50whp ...

If you are searching for a tuner, stop looking. Casey is awesome and will take the time necessary to understand your build and your goals. He is a great communicator and turns the tune around quickly. He stays with you until your goals are reached and you are satisfied. Thank you Casey. Look forward to working with you again in the future!

Vette runs great, very happy with the tune. This was my first time sending off my ECM for a tune, Tech line was very helpful and patient with my questions. Down the road if I need to have it retuned, I will definitely send it to Mailorder Tune.

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.

I can't say enough great things about Mail Order Tuner. Casey has been amazing to work with. The very first tune made our sweet little bus run 100% better! We have 2 more vehicles that we will be using them for as well! The tune on our LSA 6.2 the fastest vehicle I own!

This is the second vehicle I've had email tunes done for, couldn't be happier with customer service and their services will continue using them, great people. Casey has always been very helpful through many other issues I've ran into regarding other issues found with vehicles very knowledgeable about what he and his team does.

I haven't driven it yet. Putting weatherstrip on doors. Probably finish this weekend. But it starts great and sounds different in a good way. I know that it's from calibration for the larger injectors. Looking forward to seeing the new shift points. I've told several people about you calling me to ask about what I wanted to accomplish with the tune while you were working on my ECM. I know that it's going to be great having done business with you before and your taking the time to help me with so...
