New tune is in, 18-19psi, figured the green 15psi spring was not ideal. I put in the yellow 23psi spring.
I still get the flutter. However, I noticed it does not do it at WOT/100%, 50-90% I get the flutter. Wouldn't that point to a small vacuum leak causing the noise?
The only other thing I can thing of, there seems to be a bend/kink in the wastegate rod.
