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.

Edge Evolution CTS2 Programmer Reviews


Good Programmer, did exactly what i bought it for

Reviewed By Henry K (Celina, OH) Reviewed for a 2005 Chevy Avalanche —9/13/2016 8:23 PM

AutoAnything had fast, on time shipping and great packaging. Had a little trouble installing the programmer due to some aftermarket mods(remote start). Eventually got installed by removing some fuses and is now simple to do when switching to a different tune. Saw instant gains in MPG, around 2.5 MPG on economy tune. Also some noticeable torque, power, and acceleration gains on economy which is what I have it on most of the time. Bought mostly for better MPG and did just that.
