Default Fuel Pressure
I believe I read somewhere that the C5 LS1 has a fuel rail pressure of 58psi, please correct me if I'm wrong.
I'm wondering what would be considered an unsafe drop in pressure. 56, 50, 45psi? I am more concerned with WOT, high RPM situations but all conditions interest me.
Lastly, are there any components of the system other than O2 sensor readings such as the injectors that alert the PCM to low pressure conditions?

Thanks
