    40 psi with vacuum line on and when you hit the gas, at idle it should be around 30 - 35 psi.

    at least thats what my fuel pressue gauge say's, i just left my aem fpr stock from factory

    i don't agree with aem either.

    all fpr's need a vacuum source. honda ones are 1:1, meaning they don't rise disproportionate to vacuum (like fmu's do with boost)

    it should be about 35-40psi at idle, and as you get more vaccum from more rpms and throttle, it raises the fuel pressure a little bit
