500 rpm gain on a 12K rpm motor isnt that much. And your last 500 rpm your power diminishes. Not going to argue that a full reflash and the availability to reflash with mods and engine building is better. Arguing a reflash is one time, I personally had better gains through my PCV than quoted a year and a half ago when I was going through this. For all my vehicles I have a tuning program allowing me to reflash the ECM, EFILive, hyper tuner, Tuner studio, ECM Spy, and going to start working with UPRev in the near future. I can also data log with these. Sending your ECM out of your bike will not get you the awesome gains to make it worth the money and time it takes to do it. Now if the tuning program comes out for us to hook up our lap tops to the factory ecm, data log and tune, by all means, 100 times better than PCV. For this bike, the availability of power gains, the ease to manipulate the maps, ability to combine piggy back units, etc. are all better than sending your ecm out.
