If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, Hypertech Speedometer Calibrator allows you to re-program for correct speedometer readings, as well as correct part-throttle shifting. The larger backlit LCD screen provides quick and easy setup, and user-friendly navigation for simple navigation of the tuning features, and diagnostic tool features.

NOTE: Does not work with vehicles that have the Chrysler PAM update
