fuel pressure problems...
to start what should the 5.3 fuel pressure be?? i changed the fuel pump this past weekend, and has a new fuel filter. with that it will start and idle fine, when i go to accelerate it bogs down all the way, my pressure reads 40 at an idle and drops 5 to 10 under a steady acceleration.. i am strongly leaning to the fuel pressure regulator is bad, any thought???

i replaced the pump with a new fuel pump this weekend. the filter was changed about 5 weeks ago cuz thats what i was thinking it was. and yea it was acting up before the pump and filter.. now both are brand new and its still acting up. im stumped and i am almost completely sure its got to be the reg. but the pressure is staying right around 40 psi and drops at full throtle.
but if i gradually build up to i can get the rpms up all the way, but very slowly
