This was done at idle, booster disconnected, gauge to booster line. Let idle, then checked at 3k rpm to see. My helper is vehicle illiterate so it’s been a rough day lmfaoMy thoughts exactly especially after he says it went to 3000 revs.
Pinch the hose or pull it and plug it.
I even smoke tested and found zero smoke pushing out anywhere.
Engine also assembled by a great reputable shop in Nc.
Not sure about this tho. I held brakes and revved engine up. Obviously brake on -idle drop. Revved back up to normal. Peddle felt fine.
Under neutral revved it up And pedal pressed. At like 3k rpm. Pedal sank a little further down. Assuming bc vacuum was built and assisted pedal a bit.
At this point I’m looking at a pump to assist with added vac. Thoughts
