Superchips Cortex Programmer Reviews


EXCELLENT

Reviewed By Robert V (Pueblo West, CO) Reviewed for a 2002 Chevy Avalanche —7/7/2009 6:39 PM

It adds good power, but the real plus is the operation of the transmission and the overall performance of the car. It runs smoother and the mpg is up by two. Would say it's the best on the market. I have owned three programmers and this is the best.

Good power and Mpg

Reviewed By Diego P (milpitas, CA) Reviewed for a 2003 Chevy Avalanche —3/18/2017 10:25 AM

I order the hypertech max tunner for my 03 chevy avalanche 2500 with the 8.1 litter, just to get a little bit more power and mpg, and I was surprised with the results I haven't gone to a Dyno but I definitely feel increase in acceleration and my mpg went up 3mpg more witch is great for the price.

Jet Performance Module Reviews


Jet Performance Module Stage 2

Reviewed By marcus g (Edwardsville, IL) Reviewed for a 2007 Chevy Avalanche —2/18/2017 5:27 PM

This performance module was key to all of my MODs performing as they should. The throttle response is crisp and when pulling through the RPMs and it feels strong. The shift points are higher feels much more performance oriented. My MODs include, Jet Performance Module stage 2, Jet Performance throttle body, full cold air intake, MSD coils, 8.5mm plug wires, shorty headers, throttle body spacer, high flow cats and exhaust. I do run 91+ octane and Royal Purple oil. 5 Stars!
