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


Love It!!!

Reviewed By David S (VIRGINIA BEACH, VA) Reviewed for a 2007 Toyota Tundra —2/17/2017 5:54 AM

Bought it cause I put 35's on my Tundra and I was about 5mph off comparing to GPS. Also noticed shift points were off along with gas mileage. This calibrator not only allows you to fine tune the speedometer but it also brings the shift points back to factory settings. I am now back to 18+mpg on highway and 13-14 aound town and I am heavy on the right foot. Easy install, just make sure to zip tie to prevent rattles behind the dash. Highly recommend.
