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.

Hypertech Speedometer Calibrator Reviews


works great

Reviewed By William W (COLUMBUS, OH) Reviewed for a 2014 Chevy Silverado —6/27/2015 12:06 PM

I initially set the unit for 34" tires, the diameter of my Toyo ATIIs in 295 60r20, the speedometer was actually a couple mph over. After some downward-tweaking for tire inflation level, I setting the unit to correct for 32.75 inch tires got my speedometer accurate to within less than 0.5mph error compared to Garmin GPS. Keep in mind that actual tire diameter is dependent on how many psi you are running, so getting things right on the money may take some tweaking.
