Hypertech Speedometer Calibrator Reviews


Great tool for the job

Reviewed By Jimmy N (Rutheron, NM) Reviewed for a 2014 Dodge Ram —6/25/2015 6:39 PM

After getting rid of the performance robbing 20-inch wheels and tires and installing base model 245/70R17s, the speedo needed correction. Knowing the exact percentage of the change unfortunately doesn't help, so it's a bit of trial and error to get it right since tire height is the only usable criterion. With 30.6 inch tires, and no static loaded radius data, I guessed and used 30 inches. Very, very close. Tried with 30.25", but went back to 30, which is quick and easy with the Hypertech.
