i bought my bike and it came with a power commander uninstalled now i was thinking of selling it but everyone that has one says that its great i dont wanna sell it and in a couple months want one to but on so just asking is it really worth putting on

 

Power commanders are for fine tuning (like after an exhaust upgrade) and quicker throttle response (even stock). Usually they are not needed, especially with no mods, but ends up being preference. How much performance do you want/need?
