I put 3.73's in my 00' v6 and i LOVE them... its one of the few mods u can actually FEEL the difference. where you dont gain any HP you get but loads more "umpf" and you will be putting yourself in your seat a little deeper than before
3.73s then boost it man..dont waste time with cold air intakes and pullies..there not worth it..and get full exhaust..headers off road hpipe and good catback..personally flowmaster for me lol..and beefin up that suspension with some upper lower controls and shocks and springs..
i installed them in my car.........not a HUGE difference but you know they are there when you hammer down on her!! i personally would have got 4.10s if i didnt have to drive far every day (about the same as you)
