Performance goodies for 4.7L V8

What are some performance upgrades available for the 4.7L V8 in the Dakota/Durango?

Superchargers, Chips, CAI etc.

I am looking for best bang for the buck.

I tried a search and came up empty.

Thanks

also depending on the year get a new Y pipe made to like 2.5" or 3". there very restrictive on the 4.7L's also a new or ported TB will also help. An HO intake manifold will also help along with some cams. If you want more than that, i would also get some gears

you could also buy a Jet chip for that motor, helps adjust the gear ratio and computer. But air and exhaust are the most important steps to take first
