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.

Superchips Flashpaq F5 Tuner Reviews


Works great

Reviewed By Eric I (Spokane, WA) Reviewed for a 2006 Chevy Avalanche —7/13/2016 7:37 AM

After receiving the tuner, I updated through "ignition". Plugged in to my port, and could only get 12% download from stock settings. Called Superchips, got 5 more updates, had to unplug 2 radio fuses,and worked great. 3 to 4 mpg better on economy setting without losing power. Am going to try towing mode, and hope for good results as well. Good product, very good customer support!
