Does anyone have a particularly annoying rattle at medium throttle that is coming from the rotating waste gate valve face? Is it possible to get rid of it?

Also on a side note, My synapse BOV isn't always opening up at the right time, and in certain situations (if i am in high gear and say, overtaking someone, and slightly let off the throttle after i pass) ill get a few serious flutters. I can also hear air coming out of the turbos without flutter under the same circumstances. I know what I'm hearing and on which side of the engine its coming from. I have relocated inlets as well. I don't get flutter when dumping everything, only when going to half throttle when the turbos are spooled.

Thoughts? I don't want to do anymore damage to the turbos, so i need to get this figured out.
