I dont know about everyone else but I have a pretty good relationship with my dealer and I would just return the car back to the factory tune at the dealership and when they were done I would re-flash the computer back to the tune. And in reply to Sparty92 when you take your car into the dealership they can note you have changed items from the factory and hence mess up your warranty later down the road if something were to go wrong related with that item.
