I have a Greddy 3 row with all the piping, and my BOV is welded into the pipe on the left of the motor where the intake is. My problem is that is the screw is tightened too much, it doesn't releive the air at normal or medium driving levels, only at WOT. BUt if it's too loose, it tend to die when letting off the gas (at a stop sign for example). I can't seem to find any middle ground here. If the screw is in tight, should I worry about not relieving the air?
