Hypertech Speedometer Calibrator Reviews


Does as Advertised

Reviewed By Chad M (Midlothian, TX) Reviewed for a 2015 Ford F-150 —8/15/2015 8:16 AM

It calibrated my speedometer since I put larger tires on. It takes trial and error. Just because you put 35" tires on doesn't mean you just set this to 35". You have to test it. I have 34" tires. Had to set this thing to 32.5" for the speedo to be accurate. Unfortunately, this is my only option at this time since the tuners are unable to calibrate the 2015 F-150 at this time. Dealership wanted the same price as this calibrator for a one time change. Good product.
