Low oil pressure at idle?

What kind of oil filter are you running? Stock? Or remote oil filter? Too small of a shorty filter for clearance can cause this, don't ask me how I know.
Wix 1516 with a remote relocation kit. It's s standard tall filter,and the remote kit doesn't have any valving. Checked to make sure it wasn't hooked up backwards aswell lol. Couldn't tell ya why I would ever check that
