hissing noise after acceleration

I have a 1993 9000 CSE turbo that runs like a champ, but has a oddity that I have never before experienced. When I take my foot of the gas pedal, a loud hiss (apropos to a semi setting its air brakes) is emitted from the front end of the car.
This occurs whether or not I depress the clutch pedal following a release of the gas pedal.
I enjoy great boost and excellent gas mileage.
I recently bought this car after totalling my '92 9000T. The first thing I noticed when I opened the hood was that the turbo assembly appeared to have a few more bells and whistles attached to it than did my 1992. None of these items (sigh!) appear in my Haynes book. Perhaps the sound I hear is extraneous pressure being released form the turbo system? I don't know.
Any help would be appreciated.
Thanks,
Chris
