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.

Excellent Programmer

Reviewed By Jonn O (STACY, MN) Reviewed for a 2015 Chevy Silverado —5/12/2015 8:09 PM

I purchased this immediately after picking up my new truck, so I'm not going to install it until I get through the break-in period. But my brother has this same exact unit and it's great. Based on his experience is why I bought this programmer. They are great!

Glad I bought it. Truck runs great an a bit faster. Dose not do a few things it says it dose. Depends on model of truck. But overall it works good
