Adjustable fuel pressure regulator
HI!... I've been running a AEROMOTIVE billet aluminum adjustable FPR for years now. Due to my "99" 5.4 had a welded on non adjustable FPR fuel rail, I ended up going with a "98" 5.4 fuel rail which had a bolt on NON adjustable FPR. Just simply on bolt it and bolt on the adjustable one.

Just remember that a adjustable FPR id not a H.P mod. It just allows you to tune your set-up better than stock.

I'm researching cylinder heads now. 2v is good 4v is better and port them it's fantastic. Throw in some cams and you better be able to fuel that bugger.

I would include a higher flow pump too. I have 42# injectors and a 255 L/hr pump at stock pressure. Works just fine for me.
