What psi are you sitting at?
Recently drove a family members c5 with ls6 swap, and his car runs around 42-45psi at 70mph. Looked at mine, and I'm 55psi at 70mph. We have basically the same mods. Idling, car fully warmed up after I drive, I sit around 42psi. Why is mine higher? Should I be concerned?

I'm at 11-12psi, ohhh we're talking about oil pressure... you're fine, probably have a shimmed or higher pressure pump

And as previously stated, with your 42psi idle, you probably have a shimmed or aftermarket oil pump.

what I'm trying to say, and what skyavonee stated, is that the speed is irrelevant and rpm is what is going to determine if your oil pressure is higher or lower... 6th gear at 70mph is about 1800rpm whereas 2nd gear at 70mph is almost redline, there will be a big difference in the pressure

However, as oil temps go up (with a greater engine load), oil viscosity goes down and with it, oil pressure.
