well the pump may be bad, or the strainer is clogged.

mine runs at 40psi when moving, and 22-25psi hot idle. 50psi cold start idle.

but 25psi is bad for anything above 2000rpm.

Thank you Mr_president/tondss for posting under my name on when you were at my house.

I take no credit for your grammar.

What oil filter is your friend using? I used to have lower oil pressure, but when i switched to mobil 1 oil filter, this helped to get better pressure. I also have a 98 camaro, and if I could i too would change the oil pump just for insurance, but so far so good, just keep an eye on the oil pressure that's what i've been doing.
