First things first: Welcome!

Well, I'm just sick enough that I wrote mine down.
Seems like the equalized pressures were around 95 or so.
At regular idle Low = 23 High = 165
At higher idle Low = 16-20 High = 160
This was at 75 degrees ambient temp at the time...

This is a 1980 240D running R-12
Vent temp of 40-41
