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.

Reviewed By Stephen C (MILWAUKEE, WI) Reviewed for a 2005 Chevy Silverado —6/24/2015 8:50 PM

I was looking to buy one of the cheaper tuners and was convinced to spend the extra money on the Bully Dog. I am BEYOND satisfied with my purchase!! Increased gas mileage as well as noticeable power increase. This unit teamed with the Dynomax cat back system and K&N cold air intake on my 2005 Silverado is AMAZING!! Thanks AutoAnything!

This product is a "no-brainer" for the oil consuming GM 5.3L. Wish I would have installed sooner than 130,000 miles. No negative impacts at all and does exactly as advertised. I have actually noticed a slight increase in mpg and reduced valve clicks on start up. Car guys appreciate products that really work and solve problems....this one does that!
