Hypertech Max Energy Programmer Reviews


Daily driver that needed a little more pick up

Reviewed By Thomas B (FLORENCE, AL) Reviewed for a 2011 GMC Sierra —11/27/2014 4:28 PM

I got this to add that little extra to my truck, running the premium tune (92octane) I can tell a quicker pick up on acceleration. Fuel miles you won't really tell a huge differance until you run it on the highway, there you can tell both increased HP when passing and better Econ in the higher speeds. Overall happy.
