Hello all: I just picked up an 09 M3 coupe with 1300k on it and I absolutely love it. With that said... I am sure the honeymoon will come to an end and I will want to make her run faster. I have heard that a chip will not only void the warranty but actually flag the VIN number on the vehicle? I am not sure who to contact at BMW for the "official" word on the warranty but I really want to know what I can do to the vehicle without voiding the warranty. Anyone have some facts and/or ideas???
