i have a noise that sounds kinda like wind being blown over the top of a pepsi bottle. i guess thats the best way to explain it. it happens when im lettin into it and just lettin off while driving. it wont happen when i rev it up in park or at an idle just driving. what would that be

 

Hmm to me sounds like your turbo spooling up that would be my guess its normal if that is what you are hearing.
