Had the power commander III in my bike mapped today fro my Sil exhaust and the stock lid. the dyno tuner did a awesome jonb, the air fule ratio is perfect. the power curve is a nice smooth clim, as is the torque. the hP #s were lower than some post here, but he says his dyno #s are not inflated which is very common. the tuner alos said I could get away with the open airbox lid, it wouldnt hurt anything. I thought it would cause the bike to be lean....Whats the truth?
Try it...
I think it will be lean.
Like dp said, probably will be mucho leano.
