Vacuum needle vibration

[Mike Harrington]

I've got a slightly above stock gen VI 454 with the comp cam 212/218 in a 1989 K3500. This is my vacuum gauge reading after reaching operating temp. It's got that slight vibration as seen which to my understanding could either be ignition problems or valve issue....or as I've been reading could be normal with an above stock engine. It's a TBI with the cam and original chip....for now. What's y'all take on this reading.....the ignition system is all brand new, and the valve components are to.

Most people post a link to the YouTube address. They automatically embed I believe. Guessing the site thinks you picture is huge and said nope.
