Your stock pressure is 47-50 psi for the 420A (vacuum line disconnected), but that might be different if you're running an FMU. Here's a thread I came across with a search for "fuel pressure" in the 420A forum thread titles only, which would be helpful if that's your case. http://www.dsmtuners.com/forums/showthread.php?t=237048&highlight=fuel+pressure
