Arrow Blow off valve flutter.
My stock evo 9 BOV has started fluttering real bad at about half throttle but full throttle it holds boost like a champ. I tried cleaning it but that hasn't made a difference.

Is there a BOV that I should replace the stock one with or should I buy another stock one?

That's what I'm thinking 29PSI car has 42k miles on it.

Same thing is happening with my Greddy type R. Holds boost well but doesn't open at low boost at all...
