: Yeah, my guess is that they would fail in the off position since you need engine vacuum to open it any way.
If it does not fail either open or closed, but regulates pressure 4 psi low (10%), would there be a significant effect on performance? Have any of you measured the pressure (engine running) when the car is performing normally?
