This sounds exactly like my case. I went back to stock yesterday and tried to reproduce the code before going to the BMW service center, couldn't pull it off no matter how much throttle I gave it. Tech said to reflash again and try to throw the code and viola...
Only problem is I can't replace parts under warranty if the flash is on there when the Tech reads the codes. So starting with the cheaper-to-replace parts: spark plugs.
