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.

2015 Toyota Tundra 5.7L

Awesome product!!! Great step by step instructions. Had 0 problems with the installation, it took about 45 minutes from start to finish. I would recommend you measure your tire to get the exact size. I upgraded to a 22in wheel with 35s and programmed 35s first and it was still off 2 MPH. Once I measured and saw that it was really a 34, I programmed that in and it was perfect. Much smoother shifting too. I also noticed a 2mpg gain too!!! This is a must if you have a lift Tundra with 35s or larger
