Should be a vacuum at idle and on overrun if your gauge can show them...

Mine runs -0.65 bar ish on idle when warm.
Or that's what my data monitor says.
Does drop to -0.75ish on overrun.

A typical engine will idle at 0.3-0.43 bar absolute (-0.7 to -0.65 bar guage ) at idle, obviously any friction resulting in higher loads for the ISCV to compensate will increas the pressure (decrease the negative) so cold oil, heated rear window etc.
