I have installed a FM107 kit with cams no head work a while back. The bike ran good and I have autotune pro. I didn't bother tuning since I cannot find a good tuner in my area. My buddy Keith was talking to me the other day and recommended 2 wheels dynoworks. Nels is the man! He is so knowledgable and knows what he is doing. After 2.5hrs of fine tuning, the beast runs smoothly and gain 2hp/4tq(97hp/108tq). I am very happy with the outcome. If you live in Washington state, you should go see him. Alex
