you could also pick up a ls6 intake for fairly cheap. every now and then you can find one for less than 300 used on here. you could also find a set of used headers/y-pipe for real cheap as well. (don't forget poly motor mounts when doing lt's)
is your car an a4 or m6? if it's a4 look into stalling it, if it's an m6 look into the tick master cylinder and speed bleeder. these things may not give you any more hp but they will get you down the 1/4 more effectively. and are not that expensive.
have you deleted EGR/AIR? that's damn near free.
have you put your ride on a diet yet? there is plenty you can ditch to shead some extra pounds. ie: jack/spare tire, rear seats/belts, sound deadening, misc loose crap, etc etc.
now if you are really serious about bang for your buck then go ahead and order you a 78mm plate system from nitro dave's and have fun.
