After looking thru the posts and having some problems deciding on a power commander, perhaps some one could clear me up on a few things. I have a 04 busa and the only mods are yosh pipes and removal of the pair valve. I want to put a power commander on but i was told that the pc3r was only for the 2000 busa and that the one i needed for my bike was the pc3 w usb. i went to dynojet's web site and they dont list the pc3r for a 04 busa. Can anyone enlighten me or help me on this topic. And the reason why i am getting a pc is because the bike runs real rich. Thanks Joey
