Pretty sure it should be 39lbs across the board. Somebody correct me if I'm wrong.

depending on vac, the pressure should fluctuate between 27 and 39.
formula is 39-(vac/2)= rail pressure

there is not a set idle pressure due to the fact of the returnless style fuel system. the pressure is regulated by the fuel pump driver module. what issues are u experiencing?
