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.

Nice upgrade!

I purchased this device from Auto Anything and got the best price for it. I plugged her into my challenger rt and wow it woke her up. I went straight for the 93 octane CAI tune. Very happy with the new performance gains. A must for Mopar owners.
