Under Mid to hard acceleration, and as the turbo spools up, it makes a breathing through teeth noise, and continues constantly until the gas is let off. Vacuum leak? Turbo going out? The wind coming from the turbo does seem higher pitched and less constant than before. I do have the original turbo at ~72k Miles. I have been running APR 1+ for about 3.5k miles.

Another issue.. There is a loud humming/vibrating noise coming from the rear bottom side of the car. I'm thinking its the fuel pump/ fuel filter.

Can anyone help me out?

Humming is a failing fuel pump and/or clogged fuel filter.

Mrkrad

make sure your turbo hasn't ingested something.

DV's go bad, older ones need servicing of the diaphragm (even the SS forge ones).
