more power with less money

hey i have a 02 mustang v6 and i was wanting to no if anyone has a way to get more power out of it. i have a cool air intake on it.

me im not a fan of the v6 power mustangs, but try some headers,cat back,or a supercharger...

most deff put headers and cat back on it... there cheap and a lot of power

Is it a manual or auto because you could buy a tuner/chip and change shift points(auto) and add some hp and tq with the tuner.
