My car seems to sometimes have pretty random vacuum fluctuation, like I could be cruising and put a little load on it and the vacuum needle will almost vibrate from 9-11 hg inch or something like that

Any ideas what could cause this?

Could the big cams be the issue here?

Ive pressure tested it for vacuum leaks already and the car runs fine....just dont remember the vacuum ever vibrating like this.
