Hypertech programmer

That's pretty much all that's available.

Electric Supercharger (never tried one myself)

NOS (could be some legal issues when used on the street)

JATO (http://www.snopes.com/autos/dream/jato.asp)

but, as my buddy the gearhead sez - "No replacement for displacement"

Modified Volant intake, 4.7L throttle body, Airam power wire, JBA Liberty headers, Magnaflow high flow cats, cat back of some sort, Hypertech tuner, ported intake manifold.... I'm sure there's more, like built high compression engine blah blah blah

No but seriously, type in any questions like this in the search bar and read through.

ca07 has a good list to look into.

Just don't think by adding all of these parts you'll wake up a monster or something. But they will definitely make a good difference.

I dont think OP likes our ideas... Simply basing that on the fact that he hasn't even replied.

But in all seriousness...7 bottles of octane booster should work
