This programmer functioned as intended. It boosted horsepower about 10% which raised my average mpg by 21%. Three extra mpg may not seem like much, but when you're averaging 14 it really helps overall.

Hypertech Max Energy 2.0 Programmer Reviews


Everything and more

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.
