The old racer's adage of "10 psi for every 1000 rpms" is a good number when hot. You should have around 30-40psi, anyway, at idle, when warm. Unless you have a mechanical gauge, I wouldn't trust the electrical gauge to be 100% accurate.
Truth is, you don't really need a lot of
pressure when running....as long as it rises with rpm, that's a good sign. What you need at higher rpms is more
volume, since the spinning crank causes centrifugal force to throw the oil off the crank/bearings fairly quick. More pressure won't solve that, but more volume will.
Higher
pressures will actually slow the engine down, and cause more stress on the pump, the cam gear, and distributor gear & shaft.
