No need for a Power Commander unless you're changing fueling maps, which is necessary if you have a full exhaust system as that changes the air to fuel ratio. Cat back systems don't do this (or at least not enough to warrant changing the fuel maps), and if the previous owner already had it tuned, you're sweet. K&N doesn't make a large enough difference to warrant re tuning it either imo.
Why do you want performance upgrades? The bike can already outride any speed limit lol. My suggestions would be don't mess with the power commander, improve the front end suspension with emulators or something; changing your gearing for more low end power for more fun off the line, that kind of thing.
Be smooth, then be fast.
