Easy to install simple to use

Reviewed By james b (Ashville, AL) Reviewed for a 2012 GMC Sierra —6/27/2016 2:49 AM

Haven't seen a major power difference but has definitely improved fuel economy. Only problem I've had with it is it has froze up on me twice.

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.

Screen is the right size.

Reviewed By Frankie B (WAVERLY, KS) Reviewed for a 2013 GMC Yukon —5/18/2016 11:23 AM

Fairly easy to download and install tuner. Screen large enough to easily read but small enough to not be obtrusive. Good menu services.
