hi im new to this site i have a 05 r6, and the only performance mods on it, it a high mount leo vince titanium exhaust. i would like to do a few performance upgrades to get a little more torque, and roll-on response without dropping my top speed or runhin higher rpm's what do you suggest, how big of gains can i get from a pcIII? is it worth it? is the generic leo map good-enough? do you suggest a 520 kit? different teeth? k&n? not trying to do anything too radicle or spend too much money, but not a big deal. what do you suggest?
