On the back of the p7100 pump behind the AFC diaphram there are two screws holding a cover on what I assume is a adjustment screw of some sort. What does it adjust and is it safe to play with it?
I found the answer to my question on another forum but thanks anyway. I still would like a answer to how to tell if waste gate is stuck open.
If you still have stock fueling, it'll probably not be enough to spool the turbo up. With mods, it'll eventually spoolup, but take a real long time to do it.
