it is a type two turbosmart BOV. it holds untill i back off. it isn't a problem. it doesn't worry me if it goes off at 3 psi. as long as it doesn't go off when i have my foot down.. it may go off so easy because i have a fairly big fitting on the elbow for the hose to the throttle body..
It goes off because the air physically has nowhere else to go. The next weakest link is yout throttle shaft. If you were running more boost and had bov problems, you would probably bend the throttle shaft.
