What is that noise?
As the weather gets colder I get slightly more boost. I'm currently tuned for 19psi but ocassionally i get 20-21psi. Its a very odd noise at full boost. When it hits max boost I hear like a blow off valve noise. It makes the sound very rapidly like it blowing off a million times and very quickly. Does that mean my stock BOV is leaking? Its really hard to explain and i hope someone knows what I'm talking about. I have a evo316g with supporting mods.

Sounds like it could be a minor pre-turbo exhaust leak, most likely from the header/uppipe gasket or turbo/uppipe
