What is normal oil pressure for a 2008 5.3L AFM?

At cold idle I'm over 40 (can't remember exactly where), maybe around 50 psi. When driving cold it's around 50 psi or so. When it warms up and driving I'm right at 40 psi or slightly above and maybe right at or slightly under 40 psi at idle. If I give it a lot of throttle then I can get up to 55-60psi.

I'm currently running Castrol Edge 5w-30 w/ PureOne filter.
