Well to make this as simple as possible.

When i rev my engine up almost instantaneously the engine bogs, it does this with the bypass valve opening. Which got me to thinking, the valve opens when you start your engine due to vacuum so why is it dropping of right away shouldnt it be a graduation of the rpms?
I assume the valve should not be closing all the way at 3k rpms. The other noticeable issue is if I continue to hold the throttle open it was pass the bog point and bring vac back and close the valve and continue working as normal.

I was thinking maybe a vac leak somewhere? Any idea would be helpful
