[s-cars] A tiny noticeable wooosh! when letting up on the throttle...

[Alvin Labonite]

What comes to mind normally is BPV, correct? Well, I have one of those metal
hyperboost that's supposedly a great one and I doubt the woosh is coming
from out there. do you think it's coming from a leak on the Turbo to X-over
hose? I'ts definitely noticeable on the pass front. I know I should
pressurise the intake.

TIA for any suggestions.
