I am overall very impressed with the tunes. It took me about a week working with support to get the tuner working on my truck. The support staff was great to work with. The tuner is showing some MPG gains and it let me correct my spedo. The tuner also seems to hve added a bit of low endo power which I like. I dont tow but I do have the truck lived 3" with 33's.

I think the Diablo Sport Tuner is a great investment for the money,it does everything they say it will do. And the menus are easy to navigate. It really woke up my Silverado, the multiple truck use is a nice option agreat s is being able to turn off the active fuel management
