I have it too.. It's not a whistling.. I'd say it's more of a whining noise.. but it's very very slight, really unnoticable really, and not annoying in any way. Just sounds like a normal noise to me. If yours is louder and interrupts your driving pleasure I'd have them take a look at it. Just say that you went for a ride in your friend at works Crossfire and his doesn't sound like it.. then they'll take you a little more seriously.. I always say stuff like that "Oh I compared it to my friends..".. rather than just seeming like a paranoid customer.

Dem0, as for wind noise TSB, all it is is a new piece.. theres really no adjustment or much they can do to it I don't believe.
