Default ( (How can i get 430 hp. out of my 2004 xjr ) )

I'm looking to get about 430 hp out of my 2004 xjr. what are your suggestions ?

1. MOBIL-1 5w30 full synthetic
2. Hi flowing fuel filter (AEM)
3. Mina exhaust ( muffler's only)
4. K&N filter
( Will these add on's reflect 430 hp ? )

SIDE NOTE: REDUCING WEIGHT by removing spare tire from trunkand replacing oem battery with lighter optima battery (more cranking amps)

ANY OTHER LITTLE SMALL TRICKS THAT I'M MISSING OR WHAT DO YOU SUGGEST ?

i think the 2004 xjr makes 390hp at the rear wheel so i need to find 40 hp.
