Hypertech Max Energy Programmer Reviews


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.

Works perfectly

Reviewed By LAWRENCE M (COLUMBIA, PA) Reviewed for a 2008 Chevy Avalanche —12/15/2016 11:32 AM

Plugged my Range in right away, started driving, no more dropping into four cylinder mode! No change in fuel mileage. Exactly what I wanted & expected. Newly rebuilt engine in my truck 4 months ago I believe due to the AFM. Gonna keep truck till I go,so we'll see!

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.
