Could be the first signs of a bad sending unit too or worse.
Yeah, I was really surprised that the factory made the stock gauge look good at 6-7 psi...
Put the gauge on, and now I get about 85 psi at 4500 rpm when it's warmed up, 20 psi at idle, 50 at 2500 rpm.
Plus it'll be sure to tell you if your cam synchro is bad, maybe even fluctuate to warn of impeding doom from the synchro on its way to going **** up.
