Plug and Play!

Plugged it in and its like driving a different truck, no more waiting for the AFM to decide to switch bach to V8. Simple, easy fix to prevent future engine problem on my 5.3.

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

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.
