+1. i'd do gears and a tuner, or just the tuner first. it will help a lot, as well as help you get more out of future mods. keep in mind, if you go with the headers first, get long tubes. the hassle involved isn't worth the gains you'll get from shorties. you may as well get the lt's. but you'll also need a new midpipe to fit the long tubes...GEARS, GEARS, GEARS Will make the biggest differance over any other mod get a set of 3.73's for s/c and 4.10 for n/a, you can't believe what a gear change will do for the car.
