So I took it back. They told me it was my index 09 injectors.
Okay then. Replaced with index 12.
Problem got worse.
They told me it was potentially a plug or wire issue.
Okay no problem I guess.
Replaced with Precision Moterwerks Coilpacks and new plugs.
Problem continued.
Took it back AGAIN for some reason.

For some reason I let them "recode my ECU"

First I would flash it back to stock, cleared codes and see if any come back. Then fix what needs it.
If you can pull & clear the codes, what codes do you have now? I would down load them so you have a copy, clear them out & see what codes come back.
Also why are you using non-BMW coils, possibly adding to a problem? Are the injectors & plugs BMW?
I'd take it to a good Indy shop and have the shop run diagnostics. Let them know whats that's been done and let them diagnose. I won't be surprised if they recommend new BMW coils, new BMW plugs, and update the ECU and modules + code injectors.
