Default Turbo "phhsssss" or "whoosh" sound--Normal? Silenceable? Help!

So-- Just bought an '05 Touring Convertible, it's both my first experience with PT Cruisers and also with Turbos. That sound it makes, most noticeably when letting off the gas, which I know is desirable for some people, is just not for me. I removed the Mopar BOV, but that didn't make too much difference. I took it to Chrysler, & the head mechanic said, well, that's just the sound turbos make. There is the K & N filter/intake system on there, and the Chrysler guy recommended removing it & going back to the OEM box, said it would make it much quieter -- but that even then, the sound will still be there to some extent. But -- and here's my ray of hope & doubt -- I had test-driven another PT turbo, same year & everything, and it didn't have that sound, or any unusual sounds. So what gives?

I really hope that if there is a fix, that it doesn't make a huge impact on performance or mpg. And I greatly hope that those of you out there who know about this stuff are willing to take the time to share your knowledge here, and I thank you profusely in advance. Because I really like the car but the sound's getting on my nerves. like finding out that a great new girlfriend gnashes her teeth.
