I agree that is pretty decent pressure for the weigh poil and how many miles you have. I think they say 30lbs at idles with 5w30 is good for the low.

I ran a High Volume and had 80psi at idle, over 100psi cruising, and after it got warm I had 70-73psi at idle. I took that thing out and put a stock pump back in I now have 75 at cold and around 45-50 at warm idle, and around 60-65 while crusing, all with 5w30 Castrol.
