Oil pressure
My oil pressure seems to be kind of low. When it's at idle (700 rpms) it is a little bit above the first while line. 20 maybe? Then it stays right at 40 when I'm driving it normal. Is this a sign of a bad oil pump???

Mine runs the same pressure and has for a while a compression check was done on my car yesterday 7 cylinders had 180 lbs. and #8 had 170 lbs. I'd say you're fine. What is it @ WOT?? Mine shoots to 65-70.

No, it's very typical. The OEM guages are really nothing more than idiot guages. There's nothing wrong with your pump either. You can go to an aftermarket guage for accuracy, if you'd prefer to.

FWIW, I thought I'd throw this out.
I had 30-40psi at idle, 60-70 WOT for a long time.
Got a new PCM yesterday, installed it, drove around.
Idle is now at 20, wot is 40-60.
Is it possible a tune can change the pressure, or mess with the gauge?
I lost an engine due to 0 oil pressure, so I obviously keep me eye on this quite regularly.
Thoughts?
