NC AERO,
My CA car was around 7-8 psi when I put the guage on. I would double check for manifold leaks. Start the car cold and spray water next to the valve cover between the manifolds. Then watch your exhaust. White smoke=leaky gaskets. When I first started I found that I had leaks in numerous places. Catalyst was leaking, manifold gasket was leaking among other things.
