I'm starting this thread before I take the q60 in to the dealer so we can document what may be an interesting story. The car is modified and tuned and is now blowing James Bond style no one can follow me locomotive choo choo train smoke, and its baaaaaad. I just returned the tune to stock, Not going to try and hide anything, but looking forward to what the dealer finds. 4700 miles on the car and very little spirited driving. hear and there hard pulls and 3 dyno runs. Ill keep this updated. hopefully get some video of the smoke during the day.
