Replaced the coil in cyl 3, no help. Seems to run fine on the sport tunes, just not aggressive. Cobb states that the car is pulling timing from cyl 3 due to a mechanical issue. Problem is, it's not like I can take it to BMW and tell them there's a misfire on the Cobb aggressive tunes.
Beyond the coil and plug, what else could I be looking at?
