Got to add a chip in there, either DiabloSport or Superchip. Both will do wonders for your auto. 70mm MAF is a good mod, but you would be better off getting either a Race Header or Shorty Header/Cat Converter to go w/ the catback and flexpipe. Then you will have no restrictions on your exhaust system.
thats a good start, like the cat said, put chip into that list and take out the TB, port ur stock 1 (dont know how or not comfortable, ask a jetter in ur area 2 do it 4 u). change from the short ram mac 2 a cai type, iceman, volant, etc. i'd say ur pretty much set 4 ur 1st stage of mods. hold off on cam sprockets til u know that if ur gonna stick some cams in or not.
b mindful of those atx tranny upgrades, could b a wise move.
