Hypertech Max Energy Programmer Reviews


Some what pleased!

Reviewed By Rob W (Hamilton, MT) Reviewed for a 2006 GMC C/K 1500 —2/24/2009 6:39 PM

After installing the hypertech max energy programmer I did notice an increase in power and have increased in fuel economy by 2 to 3 miles per gallon. I changed the shift firmness 25% and this made a big difference. Overall, it's good, but not great in increasing power. I wish Hypertech would give you more instructions on what level to increase or decrease shift points for towing and non-towing.

Hypertech Speedometer Calibrator Reviews


Worked well!

Reviewed By Shane P (MOORE, OK) Reviewed for a 2015 Chevy Silverado —6/10/2016 4:39 PM

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
