Scotty,
In actual fact that is the case with any tuning mods for any model of Harley! There is such a wide variety of options available, especially for Evos and TCs, plus umpteen specialist dealers to mix and match them, that there is no single answer to any tuning question.
On the original question, tuning of a Harley involves undoing the emissions related harm done to them, which could sensibly include replacement cams, revised ignition timing, improved EFI air/fuel ratio mapping, improved intake breathing and ditto exhaust. Don't forget also that overall gearing is way over the top and can beneficially be reduced to improve performance, especially on standard/mildly modified bikes.
