I've always thought my car had kind of high oil pressure. When at idle it sits around 40 and dances to 45
Under light acceleration it is probably 60-65 psi
Under heavy acceleration it shoots all the way too 80

Is this something I should be concerned about?

Ya, too much oil pressure is almost as bad as not enough. Assuming your sender isn't just goofin up. If you actually have 80 psi., That is pushing it, but not red flag time yet. Is this on a new engine, or is this something that you just started noticing on an older mill? I intentionally run 100+ cold psi. on my GTO, but that is because the hot idle oil pressure sucks *****. Your idle oil pressure is close to ideal at 40 psi..

Car has been like this since day 1 and I am the only owner.
It probably more like 75-77psi at full throttle, but looks pretty damn close to 80

put a mechanical gauge on it such as an autometer ....iy will drop....i don;t pay alot of attention to factory gauges

Stock gauge readings FTL. Don't pay much attention unless it goes way below 40. Your oil pressure is more than fine. Nothing to worry about.

I have the Melling oil pump and mine is very high as well. I am also seeing oil consumoption. I read that if you have too much oil pressure that you can flood you engine with oil which causes consumption. Also you can blow out the oil filter. I am installing the "blue" spring from Melling to get my oil pressure back in line. I am hoping is cures some of my oil consumption problem as well.

Mine reads similarly and uses no oil between changes.
Stock pump.

was the oil pump modfied, or is all stock? if it is all stock, try a mechanical guage like the others said earlier to very your factory guage isn't off.

I am using a stock LS6 pump and have high pressure at both Idle (55 warm) and with throttle (65-70 warm) and startup is off of my 80PSI Gauge. No problem so far.

all stock, i'll probably pick up a real guage one of these days.

sounds high for on all stock pump, but put a different guage on it and that will tell you for sure.

..also what kind of oil are you using? If you use a thinner oil it will help bring it down some...the opposite if you put thicker oil in.
