Might be worthwhile porting your throttle body. I did an article for snake tales last year on how to port your own. The whistle could be caused by sharp edges in the air flow. If it doesn't quiet it down at least it'll make it flow more.

There's a few pics of mine undergoing the treatment in my gallery.

Cheers
