The state of Missouri uses the the dyno type rollers for their emission testing. I have the Porsche Stability Management (PSM) option. What damage if any can this do to the car?? Must I be sure they leave PSM turned off. Can I disable the PSM to be certain that if they restart the engine that PSM won't be active again???ThanksBob
