maximum gains? find yourself a reputable local LS tuner and get it on the dyno. don't bother with the handhelds. if you're looking to learn to tune yourself, my friends recommended HP Tuners to me, and i've heard great things about the forum community they have for them.

if you're just starting on performance mods, hold off on the tune until you've at least got intake and headers done. you'll have to retune afterwards anyway, so might as well save the money.
