[s-cars] New noise and less power :- ( - turbo chatter?

The first thing to ALWAYS check for is a torn hose creating a big air 
leak.  I can imagine that making the reed like noise you're hearing.  A 
bad BPV can result in a loss of boost but that failure keeps the air 
intake system sealed.

Good luck,
