There was a discussion about this recently but...

The specs are something like: No less than 6psi at idle and no less than 20psi at 1K rpm
Your fine

specs as per FSM is more like 1 psi per 100rpms so basically 10psi at idle. Should be around 25 psi @ 25xx rpms, then 30 or so at higher rpms. Something like that.

BTW DO NOT TRUST any stock gauges. Put a mechanical gauge on the vehicle to verify actual oil pressure.
