Do you know if anyone has put a tune on it? Sounds like they did and didn't turn off the rear O2 sensors, which is what every tuner does. How did this shop determine your fuel pressure was running low? Did they put it on a dyno and ramp it up? I mean your pressure is going to be low while at idle. Just because you have 39psi fuel injectors doesn't mean it runs at 39psi all the time. You really need to go over to www.m o d u l a r f o r d s . c o m. Remove the spaces of course. The knowledge power is there, this board doesn't have the know how to help you with your problems, no offense to anyone here. Stay away from svtperf too. All you have over there are dyno number happy people.

Oh I don't know about that, both the MACA and Motor City forums on svtperf have some very nice and knowledgable folks. ModularFords is also a great place so I would try both.

Your right, I should have clarified. However, its hard to discern who knows their stuff and who doesn't. Its a little easier on the other site.
