Who hasn't?1 (yea i know...those who have OTHER pipes) but seriously, the first thing i'd do if i were you is pull the snorkel off and add a shim to the needles and a 130 main jet. The snorkel removed will give you a power boost that'll have you smiling big time and the shim with bring it about 50% as much further still.

Mine has the snorkel removed, a unifilter with the bottom drilled so theres as much air coming in from the bottom o0f the airbox as the top, 130 mains, TBS needles shimmed to mimmick the same length as my stock needles, and 3-1/2 turns on the screws. It runs worlds better than stock.
