My oil pressure is staying 20-25 psi at idle. And I do also have a bypass filter taking a little extra oil.

Generally 1250, continous, 1500 for short times is considered ok, but without piston oil squirters, lower would be wise. Right now mine will not go above 1000 with my current ip tune. It only made it this high pulling a trailer. normal driving about 850 is about as high as it will get when going uphill.
