Well im 99.9% sure that the TCU has some issues with us tiptronics running a MBC inline with n75 or without it. A few people on vortex had the same problem and require a diode to run a MBC properly on tiptronics. Just ordered my Zener 4.7V 1W diodes. Im gonna have a few extra... anyone who's chipped already is more then welcome to get one from me for free =)
