I'm wondering if the PSI is actually low or the gauge is just dumb.

Unless you've modded the gauge, the factory OP gauge is really only a glorified idiot light. The setup does not use a sending unit that varies resistance with temperature, it only uses a pressure switch that is either ON or OFF depending on the setpoint (6 psi I think). The gauge is supposed to read mid-scale above that pressure. That all said, the gauges are funky. My 94's would do the same thing as yours (and anything in between). If you pull the wire on the switch (top of the HPOP reservoir on passenger side) and ground it, the gauge should read mid-scale. If it doesn't, there is probably a problem with the gauge itself or the wiring to it. Cheers!
