Yea it's hissing at WOT, and I'm well aware that the bov is open at idle. It's like hearing the engine sound and the turbos spools at low to mid rpms, but as soon as I go WOT, there's a loud hissing sound on top of the engine and turbo noise.....
I wish I had a better camera with a better mic.....it's really obvious when I'm in the car, even with windows up.....

If it is my bov, how can I fix it? I was thinking about changing my cp setup.....
TIA

Hissing coming from your BOV could be normal, unless the hissing is during WOT too. But at partial throttle and idle, the BOV/DV on our car is open and venting air into the atmosphere. (or into your intake with DV)
