I'm searching around for some information and found this to be interesting. I have a 2007 Busa currently with Yoshi RS3 slip-ons, stock air box, and no power commander. Tomorrow I am putting in a K&N air filter and iridium plugs. Do I need a power commander? Do you think it will run lean and be harmful to the motor?
There is a tuner close by who will tune the bike for $165 if I get a power commander. What difference in power do you think the bike would produce if I ditched the yosh pipes and went with a full muzzy, small box mod, and got it tuned? Thanks for your comments. I sort of have my own answers in my head but I'd like to have some other opinions. The tuner also told me I should think about installing new friction plates. Is there any truth to this? I am the only owner with about 15k on it. It has been ran on an 8th mile track roughly 20 passes. Other than, it's been normal street use (for a busa).
