  • 17 Digit Vehicle Identification Number.

    Must be exactly 17 digits, 9th digit must be 0--9 or 'X', and cannot contain characters 'I', 'O', or 'Q'.

    We recommend acquiring the VIN directly from the vehicle's VIN Plaque on the dash, or the certification label in the door jamb since insurance and service documents are sometimes incorrect.

  • Leave unchanged for no adjustment.

    Updates: You do not need to perform the GPS test again if your tire size hasn't changed since your last update. This includes if you switch gearsets.

    Larger tires will read greater than 60mph on the GPS.
    Smaller tires will read less than 60mph on the GPS.

    Or drag and drop your file here

    We require a photo showing the speed rating on the tire sidewall as installed on the vehicle. The speed limiter will be raised in the calibration to match the speed rating of the tire.
