    And from thr OTT site:
    No, an ECU tune cannot currently correct speedometer discrepancies caused by larger tires on Toyota platforms. The speedometer is not directly controlled by the ECU on these vehicles, making it impossible to adjust through ECU calibration.

    To correct speedometer readings, an aftermarket solution such as the Hypertech or Rough Country Calibration Tool is required.

    I stand corrected. :D
