pssshp sound

[AverageStewie]

Hello,

I've just noticed a sound on the right side of the car.. Or atleast it sounds like it. it's only noticable with the right side window open and after I release the gasspedal after my bov.
It's not happening all the time, mostly when it has built boost at around 4-5k rpm. It's a really sharp and quick pssshp sound. Any ideas? I'll try to get it on video and post it here.

It runs 21psi boost, stock turboes.

Thanks.

EDIT: Maybe this should have been in "Troubleshooting".....

But it sounds more like air...? And not a rattling sound...

I watched some videos of a wastegate rattle.. And it really doesn't sound like that. But I'll try to get it on video tomorrow..... But what do I know... For all I know it can be... But to me it sounds like it's air that blows off after i let go off the gass.

Could that possibly be turbo flutter ? From the BOV not opening fast enough. I get what you mean by the sound.
