A true perfection

GM could not solve my idle speed issues and always said OK. After a near catastrophic crash when the motor quit during an interstate rapid stop at 70 mph I decided to fix the problem on my own. This device WORKS! Also increased my gas mileage over 1 mpg. BUY IT!

Works as advertised

Reviewed By Creighton C (Concord, GA) Reviewed for a 2015 GMC Sierra —5/31/2017 9:50 AM

Really woke up the 5.3L in my vehicle using the canned tune. I have the Borla catback system as well so turning off the AFM is a plus, and the transmission shift to firm helps as well. Documentation could be better to help explain parameters for vehicles, etc. But overall I'm pleased and would recommend it.
