2010 GMC 4x4

Reviewed By Mike L (Tulsa, OK) Reviewed for a 2008 GMC C/K 1500 —4/28/2011 9:04 PM

I can not belive the improvment. It really woke up the truck. It makes the 6 speed trans shift at wide open throttle instead of a 4 sec delay. I lined it up aganst my wifes 2010 Avalanche and it pulled it by 4 cars by 85 MPH. A great product well worth the money.

Superchips Cortex Programmer Reviews


Easy to use and update- gain of 3MPG

Reviewed By Scott H (Oak Creek, CO) Reviewed for a 2007 Chrysler Aspen —8/8/2015 10:33 AM

A 5.7L HEMI is a gas guzzler by definition. That being said, I would od an add on here, another there, when I could get products on sale at AutoAnything. So, with this, and the K&N cold air system, throttle body spacer, Accel super coils, plasma plugs, and Magnaflow exhaust, I effectively went from an average of 13.5 to 19.5 MPG- in the mountains, mind you. The Superchips programmer worked in tandem with these, to give me the last three MPG average upgrade.
