Do any of you running bigger singles, run this BOV? I have it, but It doesnt sound like it does when you run the stock turbo. It just opens up and makes a surging type of sound.. I had to almost tighten the allen bolt all the way down, just to hear a little high pitch, but that is only blowing off at idle. On the stock turbo, it sounded beautiful. And yes, it is hooked up correcty...
