Default Fuel pressure

I just put my boost and fuel pressure gauges in my car the fuel pressure only goes to 50lb at idle and stays there.The car has a LPE cam and heads with 50lbs injectors,are the injectors causing the pressure to be low?or did I get a bad gauge?Is the pump overloaded with the injectors? :confused:

What year is the car? Do you have a vacuum refrenced regulator on the rail?

did you upgrade your fuel pump??? If not.. the 50# are too big for a stock fuel pump. When was the last time you replaced your fuel filter? How many miles are on the car??

that must be one hell of a cam to require 50# injectors... upgrade your fuel pump... you should see 60-62 psi.
