Hypertech Max Energy Programmer Reviews


Genuinely Pleased

Reviewed By William B (HUNTINGTON BEACH, CA) Reviewed for a 2007 Chevy HHR —9/21/2012 12:23 AM

I did some homework and decided this was the reprogrammer for me. AutoAnything had the best price so I took the plunge. Installed the program and am totally happy with the results. My "butt dyno" feels the difference. It won't peel the rubber off the tires but the performance change is there. MPG has gotten somewhat better too. All in all I'm a happy camper and would recommend this product.

2015 F350 recalibration

Reviewed By Jeff J (Diamondhead, MS) —3/26/2015 5:18 AM

I have a 15 F350 and changed from the stock 34" tires and went to 37" tires and installed the Speedo Calibrator. One thing to remember when entering tire info even if you look up the numbers in height. The stock tires are 34.1" vs the 36.54..you need to measure once the tires are installed on the truck and on level ground. My 37's once compressed are about 36.25 Entering this number got me closer to the real GPS on my phone vs running 2 mph slower at 75mph. Ill be using 35.75, to get it closer.
