I have a 2008 328xi I purchased a few months ago and interested in the AA tune. Using the simon tool, could I remove the tune and go back to stock for warranty work? I have a CPO warranty for about 2 years left still and was hoping if I got the simon tool I could switch tunes before going into a dealer. Any chance the dealer would be able to find out even after reverting back to stock tune?
