100+psi is normal when your foot is anywhere on the gas psi. Idle should be anywhere from 30ish-50psi depending on oil temp/viscosity/new-old oil/motors warm or cold.
Different pumps sizes make different oil presure too.
-10mm is usually just under 100psi
-11mm the WRX standard pump is around 100+psi
-12mm JDM type is 110-115+psi
All of their pressures drop down to 30-50 like mentioned above
