Stock N54 boost 6 psi ?

Ok, we came to same conclusion. I've already visually check the vaccum line and didn't noticed anything, but I think I'll have to do it right with a light tobe sure.

I'm not used to technical vocabulary, what does mean PID ?

I was referring to this https://en.wikipedia.org/wiki/PID_controller
If your car is OK this will make sure that you hit target boost fast and don't overshoot.
If you have a boost leak it will try to reach target boost by closing WG (and spinning the turbo faster and faster).
