Whooshing sound under the hood - not making full boost 200 10vt

[urq]

... as pointed out by others, it is most likely that you've got a leak in
the intake tract somewhere after the turbo ... 

For me the first thing I think about when a new problem shows itself is ...
what was the last thing I did?  Could it somehow be the cause of the new
failure?  So, is there some chance that you disconnected a "vacuum" line
while R&Ring the knock sensor?  The line that goes to the vacuum reservoir
would be my suspicion.  Look carefully around the area you were working to
see if something has come loose.  

Another odd possibility I'll mention because it happened to me ... there's a
hose that goes from the intake manifold log to the head for the injector
shroud air ... if this comes loose you will have a big time manifold leak.
My car ran fine below 1 bar, but the instant it went above atmospheric I'd
lose power and hear a loud whistle.  Another possibility ... check to make
sure all the injectors are firmly snapped into their seats.

I have a new dilemma. On my 200tq 10v, after I replaced knock sensor 2, all
of a sudden I'm not making full boost, and when I get to about 1.0bar, I get
a whooshing sound from under hood. Any ideas?
