what other mods can I add to my car to make it faster and more powerful. other than nitrous or S/C my current mods are listed below let me know, so I can get these and install them over the winter thanks,
I'd say full exhaust, pulleys, T/A, and 3.73s/4.10s. With those mods, a 5 speed will dyno around 260 and the gears will get up into the powerband.
like everyone has said; l/t's, plenum, cams & a tune but one thing you may want to consider, is gettin grid of that cold air. i have seen more than one dyno sheet where people took their mac cold air off & actually gained power. if your going to be on a dyno for a tune, it couldn't hurt
