Older post, but answered one of my many questions, that being that tunes for touring and roadster are not interchangable! If anyone can help me with my other question, I would be very greatful! I have a 2010 Touring with the factory tune and would like to know if there is a tune that will unrestrict this thing? It is totally stock, I am going crazy reading all these tune posts. tune 20364 looks like the proper one, but then you read up on it and it says it accomplishes nothing more than the factory tune. Please HELP!!!!!
