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!

Awesome service and great communication. He took the time to call me and go over the issues I had and was able to fix some things that another "tuner" had screwed up. Had my PCM back in only a week after I sent it out, plugged it in and my truck runs better than it ever has. Highly recommended!

First things first, the Customer Service at MOT is top shelf! From the first call to them I was sold. Tamera answers all phone calls and is very polite and helpful. If she says she will talk to Casey and call you back, that is exactly what she does. Casey got my tune right on the first try! I've had work done by several performance shops and remote tuners and Casey seems to be the best by far! Don't hesitate to give him a try, I promise you won't regret it and you'll be proud you did once you re...
