Hypertech Speedometer Calibrators

Keep Your Car Legal When Running Non-Stock Tires

Hypertech's plug-in calibrator properly tunes speedometer and odometer settings. This provides accurate speed and mileage readings when driving a vehicle with non-stock tires and/or new gear ratios. For an additional fee to Hypertech, the Speedometer Calibrator can be upgraded to the Max Energy Programmer specific to your vehicle.
