Immense improvement in performance on initial tune. I am really quite pleased.

I haven't used a tuner before so I don't have anything to compare it to but this one is easy to use fairly easy to install. had to pull some fuses to install it but otherwise pretty it's been pretty good. my truck is much quicker than it was and leaving it hooked up is cool I like having my truck data displayed for me. oh and the driving coach is awesome although it beeps alot when you drive fast
