Hypertech Max Energy Programmer Reviews

Just what the doctor ordered.

Reviewed By Bob C (Saint Paul, MN) Reviewed for a 2002 Chevy Silverado —8/24/2011 8:17 AM

The programmer changed my Fusion completely. With the regular tune, it added the majority of the power in the lower RPM's, just where it spends most of the time while driving. My wife insists that the car runs "smoother" and acts like it has a bigger engine. There is a hill that always caused the car to downshift while ascending at 50 mph with the cruise control on, but not anymore! Mileage appears to have increased on the order of 1.5-2 mpg.
