Never heard of a 5.4L engine. The typical performance route is air intake and headers/exhaust followed by a tune. Next is usually a cam. However, not only do you have huge heavy wheels to deal with, you also live in Californication which limits you to CARB legal parts. Not a lot you can do about that I'm afraid. You can still do shorty headers and a tune, that's good for maybe 25 hp.
