How do your cams and porting compare to the GYTR ported head+cams?

Don't smack me in the face, I have a feeling your work is alot better but would like the details as I'm sure others would too!

The Bike as tested on the dyno lacks torque down low even though its very quick reving the engine seems to have light crank mass.the cams that i desighned are shorter than stock duration and and produce more bottom end as well as top end .the stock head has an abrupt short side and did not produce swirl paterns like mine the head starts out with 106ccs and with the work i did still ended up with 106cc and flowing consideably more air the gyt head is a cleaned up intake port with even more volume the exhaust port is hogged out pretty good reducing velocity even more.a good example of engine effincency is the fuel required to make power i am up t 5% leaned @the top from stock and have taken timing out and still maKING 60 HP AND OVER 37 POUNDS OF TORQUE.

I was quite concerned about that when i saw the limited avaiability of adjustment but after tuning with it and seeing a good AF ratio and and getting good power results im determined it will work great with our kit .

Just to let you know the website is not finished and it will change as we update it every day. The only people who even know its up are those who heard about it from Ron here on Thumper Talk. You can order on it now. In the spot for the coupon code just type in ronhamp and it will automatically give it to you the discount. Also if you have any suggestions on what you would like to see in a website like this let us know. Thanks TUF Racing

Do you offer a map for the power commander 5?
Also what air filter were you using? did you have to do the air box mod (drill little holes in the air ducts)?
