ECU flash tune VS powercommander /dyno tune diference

[Camel]

I've flashed dozens of Hayabusas, Gen I and II, using both ECU Editor and WRT. I've flashed my bikes more times than I care to remember. I've been tuning multi-cylinder race bikes since the late 70's. I much prefer using a laptop over changing jets and advance springs. Speak to any of the Busa owners whose bikes I've flashed. They'll tell you the bike runs smoother than stock and has more kick. Personally I prefer WRT for the street bikes as you can maintain cylinder offset and gear based maps. It comes down to cost and pose. You can fork out big bucks for a piggy back and show everyone that you have one. Or you can pay less and feel the difference. But you won't have anything to show off except a drag strip tab.
