When the throttle body closes then you will have a heavy vacuume on one side of the valve and boost on the other. This will force the valve open and bypass the pressure. Obviously this meathod works for us, given the performance we have shown with the car. If we had slow response and boost leaks then we wouldn't run the times that we have. All of this was with the stock BPV.
You know what, you're right. You have a drag car, and the effects of the slow leak are
nominal especially when youre WOT most of the time.
For a daily driver, it is better using the stock lines.
Edit: And several of us (Maybe 5?) dynoed 2 weeks ago with stock routing over 19PSI without any leaking.
