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.

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.

Hypertech Calibrator keeps it all legal

Purchased this after having my son's truck lifted with 35" tires. We wanted to capture his desire to have the look of a big truck while still maintaining the correct speedometer readings and transmission shift points. The system does require you to use a Windows based PC to update the unit to the most recent software package (it is not Mac compatible), but other than that it is very straight forward to use. Hook it to the OBD port, input your tire size and allow it to update your ECM, that's it.
