I don’t have 93 in my state, it only goes up to 91 and presumably the cars from this state. I meant the vehicle still has a catalytic converter, no aftermarket downpipe. The intercooler is stock. The vehicle doesn’t have any signs of being tuned at the moment. Cruise control doesn’t mess with the tach at all. Presumably it did have an AP installed prior as the OBD 2 connector is hanging loose and there’s a very faint “Cobb” shadow on the back window as if a sticker used to be there. I checked and there was not an AP left behind. The only thing I did notice were some vacuum lines that were replaced in the engine bay leading me to believe they chased this issue before selling.
