I don't understand your comment. If I understand the flying saucer, it opens in response to 21 inches of vacuum from a small vacuum line...and only when the throttle is completely closed (thus, de-accelerating). When properly functioning, boost does not and will not open the valve - not unless the diaphram is ruptured, in which case you would see a perpetual high idle from all the air being introduced.
