Ive driven around doing errands last night and today. The stumble at 3K is pretty much gone and the engine is smoooooooth going past 3K (the way a BMW inline 6 SHOULD feel). If it keeps up I think I can conclude that it is the cars reaction (knock sensor reaction?) to my DISA flap flying open once it hits 3K. And if the DME fix that people get just keeps the DISA flap open I might just leave mine unplugged in the long term. I don't really notice a drop in torque, either. Ill probably plug it back in in a week or so and see if that changes anything but if not Ill unplug it again.

My DISA is new (replaced it a year ago or so), and I think thats when I started noticing the stumble. I probably shouldn't have spent the money on a new one. haha.

Wait, So all I have to do is unplug the DISA... Sweet.

I replaced my DISA and just about every other component intake or vacuum related so was bummed the car was still struggling around 2,800 and 4k rpms.

Worth a shot for you. Takes seconds. Every car is different. Mine appears to not have a 3k stumble anymore

After you disconnect the DISA electrical connector you might also want to consider clearing the adaptation codes and then driving it hard for a few days to reset the car while achieving a more aggressive style adaptation.

How do I CLEAR the adaption codes? I don't have INPA.

Interested too. I have PA Soft, Can it be done with that??
