Hypertech Max Energy Programmer for 2008 H3 Hummer 3.7L

Reviewed By Shawn J (CLOVIS, CA) Reviewed for a 2008 Hummer H3 —8/13/2014 11:57 PM

I wanted something that I could program myself instead of sending of my PMC to someone eles to program. I was able to change my tire size to compensate for the 33in tire I installed, also was able to change my shift point and shift firmness as well. It also came with two performance setting, an 87 and a 91 octane. I used the 87 octane in my 3.7 liter and I got a boost in performance and mileage as well. Which made me very happy.

It does exactly what I bought it for

Reviewed By Colt C (Harrington, DE) Reviewed for a 2014 Chevy Silverado —11/10/2017 2:46 PM

I bought this to turn off the afm on my truck and it does exactly that. I have also been able to read an engine code with it already as well and worked great. The reason for 4 stars instead of 5 is because it seems to mess with the truck electronics while installing the tune (dash lights flashing, service stabletrak), which I don't know if its normal or not but worries me, so I will just stick with the stock tune with the afm disabled. Autoanything was extremely helpful with the purchase.
