The Greddy type-s is a small BOV, the flutter is the valve plate bouncing up and down and/or compressor surge, not a good thing.
Here’s a good explanation of the valve: http://www.dsmsource.com/forums/show...threadid=51052
Would a stock 1g work better on a 91 tt stealth you think? I've got time, and money(kinda) to get a new one. Don't need that loud "PSHSHSHSHSHSH" sound, but i do want a bov that works recirculatory.

I have a comfident idea that it isnt comp surge. And as in the link you gave me he talked about not holding boost n such but I hold boost just fine. My only thought to this is maybe from under high boost when I make it flutter I am over stretching that membrane too much but then again there is a point as to how far everything can travel before it bottoms out yes?
