fuel
I have an aem fuel rail with an aem adjustable fuel pressure regulator and I just got my fuel gauge. The gauge reads at 32 on idle and jumps up to 42 on wide open throttle. Are them numbers good? If not, what should it be running at?

i always thought there was more like 70 coming to the regulator and that it adjusts it accordingly to manifold pressures - to up the pressure to injectors - i thought much closer to full...like high 60's . any boby correct me ?

At idle the fuel pressure should read between 32 and 39 psi, and at WOT it should be from 41 to 48 psi. So you're fine.
