fuel pressure dropping

I got a 2003 6.0 here a about a month ago and it was already studded. I put a sct and got matts tunes and the srl++. I finally got my gauges installed and I am seeing my fuel pressure is about 51 at idle and then I think I saw it get to 42 at WOT. The fuel filters were just changed also. So i'm thinking an air dog II is in y near future. Im planning on running 190's and I don't know what turbo I want yet.

first things first, i'd get the Ford updated fuel pressure regulator spring kit, your spring is worn out it seems, thats why you're seeing a rapid drop in pressure. Do this before your current injectors hate you and kick the bucket. with 190's an airdog is a must with crossover lines. Lots of people are having great luck with the powermax turbos, especially with 190's

If you are planning on getting 190s just go ahead and get the Airdog II

I put the regulator kit on and it now is around 66 and idle and cruising but i can still get it to drop to the low 40's i think i even saw around 38 at around 90 mph then once it shifted to over drive it shot back up

You could also try installing the 6.4 banjos.

The banjo bolt upgrade will not make a difference in the fuel pressure you are seeing at the gauge... but it will let more fuel get through to the injectors.
