Cobb misfire ?????
I have a 08 335i that's still under factor maintenance and warranty as well as the extended warranty,the car has 38k. But anyways with the Cobb the car gets misfires and throws check engine soon codes,which is most likely from the plugs or bad coils. It does not do it with the car on a normal tune. Is there a way to have the Car do the misfire and remove the Cobb but keep the codes so BMW sees them??? I brought it to them with the tune removed and they say there's no issue

When you uninstall the Cobb AP it deletes all the codes. If you're getting misfires across multiple cylinders its almost certainly the plugs. Buy some plugs and DIY.

Gotta replace your plugs, my car was misfiring on Stage 2+ and on Stage 0/Stock it was completely fine. If you don't want to pay out of pocket for the replacement plugs, challenge the Service Dept & ask when was the last time they changed them. Kiss the SA's ass & you'll be fine.
