Sounds a little low to me but isn't the pressure switch set at 7 psi?
If it were me, I would try a heavier oil, Mobil 1 5W50 or 15W50. 5W50 is Porsche approved in our cars. You'll most likely get a couple (2-3 psi) more at hot idle. How about the oil filter? What is your setup? Stock or aftermarket?
Walmart has Mobil 1 15W50 on special for $27 for 5 quarts.
