I saw a z06 with just headers, hiflow cats and tune make 495 whp.
A couple of months ago, my oil pressure dropped considerably. I was at 10 - 12psi at idle, and around 30 - 35psi while driving. I had the car towed into a dealership immediately, and had it checked out. After a day of testing, the guy called me back and said that GM spec was 6 psi at idle, 17 psi up to 2200 RPM's, and 25psi above that!! I told him even if that was the case, my pressue still dropped to just above 1/3 of what it used to be, and I wanted them to find out why. He kept it another day, and pretty much told me "Sorry, it's within GM specs....there's nothing to fix. If you think there's a problem, just keep driving it....drive it hard....and if it blows up, we'll give you a new one"

2 months later I spun 2 bearings on the highway. Needless to say, I'm pissed. This could have easily been avoided.

Now I am idling at 30 psi completely warmed up (oil temp above 180) and around 50 - 55psi while cruising completely warmed up.
