    04 tahoe gear ratio

    Can somebody tell me if credits are needed to alter the speedometer calibration on an 04 tahoe? This would seal the deal on purchasing. Thanks

    Yes, credits are required to license/flash your vehicle, no matter how big or small the change you want to make is.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Writing anything to a module takes credits.
