Works well!

The Range AFM Device has helped with smoother shifts by keeping my engine in V8 mode is the biggest thing I have noticed.

Hypertech Max Energy Programmer Reviews


Hyper Fast.

Reviewed By Jeffrey F (Schenectady, NY) Reviewed for a 2008 GMC Sierra —8/28/2014 12:54 PM

Fast shipping. Excellent value. Only issue I had was having to update the programmer new out of the box? Otherwise easy install. Using the econ setting so I don't necessarily feel a performance gain but hoping for better fuel mileage. Only programmer I use is Hypertech.
