Your fuel pressure should remain constant at any RPM range. It will dip for a brief period of time as you change throttle position untill the fuel pressure regulator catches up. The LT1's changed fuel pressure using a vacuum signal, but the LS1's just run a contast pressure.

Ryan, since my fuel pressure will remain constant can I just measure it at idle after the car reaches operating temperature? If so, then what type of gauge should I use?
