Hissing Sound, T44TQ

Bob,

Thanks for replying. I'm not sure if it's a vacuum leak, as if it were
on the intake side, then I should not get anything greater than 1.0 bar of =
boost. I'll go through those things, but I think it's possibly an exhaust l=
eak, probably after the turbo, as I nearly (1.7 bar) get full (1.8 bar) of =
boost. My question is then, how do I find an exhaust leak in the convoluted=
 confines of the T44 10VT engine bay? Or is there other common locations fo=
r leaks? The leak is outside of the car, b/c it is quieter when the windows=
 and sunroof is closed. I imagine that right now, if I pass by someone when=
 I'm on the boost, that my car sounds like a very hissy, angry, fast moving=
 snake....
