Just got my car back from getting new flywheel, clutch, springs installed as well as an angle gear and collar gear serviced. I've noticed a loud air flow sound in the cabin that wasn't there before...it sounds like the turbo...and increases in volume with the boost pressure, but I can't find a leak. Boost readings, at idle and on the throttle are as expected. Any suggestions? It sounds like the noise is coming from the driver's side air vent, which is where the hose is routed though...but again, no leaks that I can find. Based on the volume of the sound, I'd expect there to be noticeable change in pressure. Suggestions?
