I am going to follow this as well. I fixed my noise by replacing the valve under the intake. But I still occasionally hear it at 3000ish rpm. I think that it may just be the hole+speed of air = perfect setup to howl.

I hope that someone figures it out eventually. As like most of you I am tired of throwing money at it.
