Customer service is great Ryan,stef,Logan and Kory have gone above the line to help me get my truck dialed in working with me after hours when I have time, would definitely recommend if your looking to qualify tcm tuning.

10 out of 5 stars!

Ryan and Team did a awsome job with my TCM tune. Needed some assistance with the install, very patient and professional. Truck can put the power down to the road now, couldn't be happier!

Fast service! Trans tune really woke up the ole duramax. It doesn’t shift out so fast and feel like it’s struggling. Enjoy driving it more after the tune. Better acceleration and performance.
