Superchips Flashpaq Tuner Reviews


Easy install and start up

Reviewed By Darrel H (PASO ROBLES, CA) Reviewed for a 1999 GMC Suburban —8/22/2014 5:45 AM

It was as advertised. Easy to hook up and so far works perfect. I was able to do a milage tune , then a performance tune and could feel the difference. Also cleared an engine code. Excellent piece of equipment.

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.
