first thing you ought to do is check locally for anyone who has the capabilites of tuning a V6, cuz not many are or don't have much experience, plus the power programmers out are not supporting the v6 yet.
i haven't heard of any cam swaps yet.
your best bet is a cold air intake, exhaust, and if you can find a reputable tuner, get headers and a tune.
there are several intakes for the v6 to choose from. the ones i would recommend are either the Airaid or Injen. for exhaust, get a cat-back system. go to youtube to find the sound you like, i would recommend magnaflow, MRT, borla, or corsa. for LT headers, hands down American Racing
; that was an easy choice.
you might be close enough to NY to visit Chuck's Tuning, he is a legend up there from what i here.
next step would be the looks of the car: drop springs or coilovers if your brave, some sweet wheels, maybe even some different color halo's from AAC... look at me spending your money
best of luck
