Bad Oil pressure switch?
I've been searching around about signs of a bad oil pressure switch and all I've found is that they'll peg completely high usually when they're bad. Well I just bought my Z06 and I'm curious about my oil pressure. On a cold start it'll go to 40 and at WOT it'll climb it just seems very slow to react. Even on start up the gauge is just very slow moving. Hot idle it sits around 26-30. Is it possible the switch is on its way out? My LS1 Camaro and Trans Am both react very quick at wot throttle. The Z's gauge is a lot slower. What do you think?

IIRC the fbody oil pressure gauges are glorified idiot lights. They have a huge "insensitive" range around the mid reading. So if you're seeing them snap up quickly, what you're likely seeing is the gauge finally deciding to react to a pressure change that has been gradually building up to some threshold. The C5 on the other hand has a real gauge. (And your pressures are fine btw)
