I wouldn't mess with the transmission flash..you're stepping into a different court. My good friend is a head mechanic at an independent shop now and was at a BMW dealer. He has the same exact software and reading devices that the dealer has...yesterday I cleared my codes and removed the JB4, nothing came up at all on his system. This is if they are looking for it too. Rarely will a mechanic dive into your ECU either but you never know, they are always curious. The JB4 made my N55 335 M sport a new car, period. I have two years left of manufacture warranty and a CPO warranty...I plan to keep the tune in and for $500, it's easy.
