Hypertech Max Energy Programmer Reviews


Good power and Mpg

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.

Hypertech Max Energy 2.0 Programmer Reviews


Hyper tech 2.0 programers

Reviewed By Steve R (Tucson, AZ) Reviewed for a 2007 Chevy Avalanche —1/19/2016 7:34 PM

I bought this to bypass the G.M. Active fuel management system. Instead of going to the stealership I purchased this programer to set the computer to the v-8 only setting. This repaired the 4 engine codes I had set on my computer. The Avalanche kept turning off the fuel to four cylinders and setting the check engine light . The engine runs great now and this is a bargain 20 minute repair to program the computer. Ten days now the 5.3 runs like a top and no codes . Thanks Again!
