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.

The ease of the installation is hard to believe. Then you start up your car , and away you go. The instant I took off in my hummer I had a huge smile on my face. I then took my daughter for a ride and watched her face as I gave my truck somme juice---and she said " dad what did you do to "Jake" [my trucks name} "? I told her about your programer, she said " AWESOME" !

Reviewed By Philip A (MANSFIELD, PA) Reviewed for a 2014 Ford F-150 —8/25/2016 6:30 AM

Essentially needed the programmer to adjust the tire size so speedometer read correct after adding raptor tires and rims. While adjusting the size I installed the regular fuel program and to my surprise I'm getting about 2 MPG more. The guy that sold me the raptor rims lied about the TPSM still being stock installed (they were gone) the Hyperteck programer let me just turn the TPSM function off instead of costly installation of new ones (why can't people just be honest). Very satisfied.
