[miller92063]

check my garage for specs.

no ideas?

I would cut and paste your mods. Some of us are too lazy to go to links to look for them.

Good luck.

43.5 psi. In the long run it won't matter much unless you go seriously low or seriously high, as the EEC will adjust the fuel trim to compensate. I say 43.5 because that is the pressure at which the injectors are rated.

Rail pressure = injector pressure + manifold pressure

In other words, base your fuel pressure needs off the desired injector pressure/flow and the amount of manifold pressure you experience at WOT.
