I need to know whats the ideal fuel pressure for my fc.
s5 t2
720cc/1600cc - 340lph -6an line parallel
15psi - gt35r - 350rwhp
stock port
idles at 1900rpm
right now the fuel pressure is at 40psi at idle. when I bounce the key on and off the fuel pressure is at 35psi.
is this good or should I bump it higher?

Aftermarket fuel injectors are typically rated at 3bar (43.5psi) so you need to run them at this fuel pressure in order to yield their advertised static flow rate. I don't see anything wrong with 40psi as long as it produces enough fuel for the engine and the fuel injectors are below 80% duty cycle. Most fuel injectors can run up to 4bar (58psi) before injector life and spray patterns are adversely affected.

Um, what?
