Hello members & sponsors.

What is the optimum fuel pressure after the car is warmed up and at idle ? Does the fuel system design (aftermarket) play a role in what the fuel pressure reading should be ?

I have a twin pump fuel system with rails and 950 cc injectors. I would appreciate any informative answers.

i believe 52 psi at warm idle is fine.
