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's alive

Reviewed By Carey Y (HARVEST, AL) Reviewed for a 2015 Chevy Silverado —3/3/2018 5:05 AM

Great programmer at a great price. Easy to use for just basic and if you want to tweak your truck a little bit you can. Glad it allows you to disable v4 mode. That alone will make a difference in throttle response and smoother ride. Great you can also check for any diagnostic. So no need to drive to auto zone and wait.
