Ok, so I swapped out my IC piping for some hardpiping. I wasnt planning on keeping it in there, just testing things out. So I take out the hardpiping, and put back in my stock stuff. With the stock piping back on, my car is like, struggling to stay on. It will either Struggle for a little while, and maybe eventually die. Or it will idle surge for a little while. Yet when I normally drive, it rides like normal. No big loss in boost pressure either. Any ideas? thanks everyone.
