Default 2015 wrx boost flutter Gfb bov

Hello everyone,

I have a 2015 wrx stock turbo full bolt ons and I'm trying to trouble shoot a boost flutter issue I'm having with a Gfb hybrid bov. When I'm at high boost it flutters 1 to 2 psi. Does this mean I have spring adjustment too tight or loose?

I have done a few runs and increased the spring rates a quarter turn each time but it doesn't seem to be fixing it

That could be the fluttering you are hearing. If so, that is normal. As for boost fluctuations, mine has always done that from stock to stage 2 +. I have been told it is normal also.
