At idle thats pretty normal at normal operating temp. It actually says in the owners manual that oil pressure will range from 20 to 80 when warm.

perfectly normal at idle. my stock gauge reads 15 at idle and doesnt move past 40 at wot. i have a mechanical gauge to, and it reads 18-25 at hot idle, and 60+ at WOT. that is lower than most engines run but normal for an lt1.

Mine reads no lower then 20, and goes as high as 40 to 70 depending on rpm. This is fully hot.

As long as it doesnt read 20 and ur doing say 80 your fine, if it was that engine is prolly on its way out.

Mine is anywhere from 18 to 25psi at hot idle. It just depends on the day the sensor wants to piss me off. About 2k to 3k it is at 40psi. Above that it is 60 to 70psi.

You might even try replacing the sensor. It is common for it to show lower oil pressure with age.
