Best Tuner on the Market

Reviewed By Steven Y (Haleiwa, HI) Reviewed for a 2015 GMC Sierra —6/7/2016 1:52 PM

I owned a I-1000 and it was ok. This newer on is faster and you don't have to press extremely hard for the buttons to respond.Also going back to stock is way faster than the first series.

i would have thought that you could adjust between performance , towing ect. without redoing the whole set up. other than that i am completely satisfied.
