sorry e:
pcv=power commander V, the latest version, google for best info.

Hey Ellis: I am 100% happy with my mod. I did it mainly for sound as the stock exhaust is weak to me. My tone is not as loud or deep as the 2Bros. Mine sounds a little more raspy like the MotoGP. I would rather spend the money to get additional stuff. Other guys have done it too and are pleased. Got a good HP reading as I ended up doing PCV and KN with dyno tune. GL
