Well I'm quite positive that the culprit of my "blowing over a glass bottle" and goose honking sounds are coming from my bypass valve. It's gotten to the point where I can pretty much recreate the sound any time. I just have to get the boost gauge right smack between white and yellow and "hooooooOOOOO!!!!!" And sometime when I let off the gas or the car shifts it makes a HONK.
I just ordered a new one, but I haven't really noticed any obvious performance issues with the car. No check engine lights, and it doesn't seem to be running any rougher than it ever did (it's never been real smooth). Anyone ever replace one of these and notice a big difference in throttle response or other fun things like that? I figure something must be sticking or leaking in mine. Thanks!
