It used to be, anything over 10 at idle, and then an additional 10 PSI/1000 rpm was considered 'acceptable'. On the newer trucks..... I don't know if that still holds true. What numbers are you seeing?

Seeing 10-11 but it's low enough to set off the check gauge light and drop the oil gauge when I slow to a stop at a stoplight. And I did replace the sender switch already.

Ran it a little longer this time with the mechanical gauge still on. It goes all the way to 6 psi at idle while in gear. Still a sender unit problem or is that too low?

Min oil pressure PSI at curb idle is 4 psi. At 3000 rpm you should see 25 to 110 psi.
Are you getting noise from the engine; rods, lifters, something mechanical?
Have you changed your oil and oil filter?

No noise at all and runs great. Changed oil and filter right after I got it. (I've only had it 300-400 miles total)
