I have a 2002 B5.5 passat 1.8T. when i accelerate there is a loud constant whoosh sound coming from under the hood and i have slow acceleration(Very slow unless in first). I am going farther and farther away from it being a boost leak in front of the vaccum line because im still geting a readout of 10-11 psi on my boost gauge, and i spliced the gauge line in the middle of the vaccum line. so im thinkin its leaking from after the vacum line. Any ideas.
