That was with regular knob tires on it. Not the dyno tires. I don't really know how much they help.

I'm pretty sure the dyno tires would have read a little higher?

ya it would have read a little highter since there a lighter weight. prob around 2hp higher from what i have seen in the past

I have to say I am pleased with it. It don't have the stumble on the bottom end anymore.

Not bad for a good pipe, ecu, 06 intake cam and fci. I bet it runs alot better now all tuned in. Still looks like the power curve drops up top like most of the YFZRs do even with the ECU. Any plans on some more mods like maybe a bored TB or porting?

No not right off I don't. I might look into getting the tb done if it helps much.

yea about 9 it starts to fall back off. I dont know if a cam would help out on the big end or not.
