I want to put my FPR on but it won't clear the EGR valve, how can I safely get rid of that damn valve???

Why wont it clear the egr? Hmm Ill be quite I do have a spacer on my intake.

Well Im still working on it, but you have to turn it off in your computer, re-tune your computer, and buy or build a block off plate for it.
i can get a pic of my block off plate if thats the route you wanna go.

save yourself the trouble. an adjustable fuel pressure regulator is worthless. you cant tune a car with fuel pressure. you have to tune with injector pulse width which can only be done with a tuner (pms, tweecer, etc) or by a custom chip from a dyno tuner. youll be sorry if you remove the egr because it helps with daily driving and doesnt hurt wot performance because at wot the egr valve is closed.

So you're saying that me and half of the other guys on here just wasted their time By setting their fuel pressure??? Primetime5.0 said that he felt a difference when he monkeyed with his fuel pressure (I can't remember if he leaned or richened it up just a tad).

the only thing you can do with a FP regulator is lean it up.
Now it probably keeps it at a steadier PSI than a vacum, or automatic, regulator bu tim not sure on that.

Oh, I learned something today . So should I just leave it at 39 psi???

getting back to your question the best way is to buy the egr simulator plug and plug it and get a block off plate

forgot about those. I guess you could do that also.
And yes, just leave it at 39psi
the only time you would need an adjustable is if your wanting to run 40+ psi. Thats usually when you start getting into your power adders and stuff.

mine made 22hp and 20tq more when I raised my timing 2 degrees and lowered my fuel pressure to 30psi, from 40psi.
while still being a slightly rich 12.5-1 A/F ratio.

the only problem with that is the injectors have trouble atomizing fuel at low fuel pressures. if your at 30psi at wot, with vacuum on your at idle will have much lower fuel pressure.

everyone says that stock fuel pressure is 39, mine was 42psi. i got a kirban afpr because everyone said you have to have one for tuning...BS! my pms does all the tuning i need. but anyways, when i got the kirban it said stock fuel pressure should be 42 and sure enough, it was
