Sounds like you need a different air intake. I have an aftermarket on mine, and it really screams without that silencer ring. How choked up is your filter? Just an observation also, I hear a lot more screaming out of my turbo below 10psi than at higher boost. Of course that could be due to some rather annoying high freq. hearing loss I have...

the filter is clean. it completly took the whisle away when i took the ring out. no matter much or little boost there was no whistle without it. with the ring its louder than hell
