pneumatics help please.

The gauges will show you the pressure of whatever they're connected to. Are you asking how to change the pressure to be what it's supposed to? That's what the adjustable regulators are for.

If you have the compressor wired and controlled according to the robot rules, the "120 PSI" part of the system will actually vary from about 95 to about 115 PSI as the pressure switch activates and deactivates. The "60 PSI" part of the system will be set by the regulator connected between the high-pressure storage side and the "working pressure" side.
