I have a PCIII USB and a HMF Dual high mount exhaust system and went down 1 tooth on the front sprocket of on 'o5 Busa. No air box mods and still have the OEM filter. Do any of you guys have any idea how much of a Horsepower gain I might achieve with these mods. There is not a Dyno anywhere down here that I know of. At least not in a coupla' hundred miles. So I'm guessing here. Has any of you guys done something close to this to your bike and found out what the horsepower is after. I know all Busa's are a little different. So, again, just an educated guess from the board.
Thanks,
David
