I believe the ambient temperature is causing the difference between coaches.

Here's what it does.  Video starts about 15 seconds into a cold startup.  Has not been run in 2 days.  Dash gauge mimics what the VMSpc shows.

I don't have an answer as to why this is happening but, I know oil pressure doesn't jump instantly from 35 psi to 61 psi. with the rpm staying the same.

So it changes after there is a buzzing sound in the background. I'm suspecting that converter box is making the noise? Weird. It doesn't climb up, it just changes again weird

The buzz is the oil pressure analog gauge in the dash moving from 35-60psi.  Stepper motor I'd imagine, but that's what the dash gauges sound like when they move.
