I would agree that they dont make massive amounts of differece to power figures, but as said before they do smooth out a few things that are there because of manufacturing constraints due to emission rules. If you are putting cans on it I would say definately put one on with the bike on map 2 or use an oxygen sensor eliminator if you dont get the map 2 put in. I have tried power commanders on a few bikes ( Gsxr750, Zx6r, Zzr1400,Rsvr1000) and always run them on a dyno before and after fitting and it is always the same outcome with slight increases here and there but the main difference will be in the fuelling ratio as you want it to be as near to 14:1 as possible and this is what they are good at. It will smooth out the throttle response but you should make sure the throttle bodies are balanced properly as well as this can make a massive difference. If you are after better fuel economy then I would say you wont get it from a power commander, if you are after a better ride then I would say fit it, hope this helps
