    From talking a couple times with Tommy Jordan (2fast4u) I gained a little over 6mph. I would def talk to him. Other than that, alot of info can be found searching the board.

    this is a winter mod that needs time and patience ,perfect,...from what I can feel the raised areas by hand near the trim tabs need the most flattening...do you guys use a straight edge going straight back...what are we looking at when it comes to mph gains..

    speed gains differ a great deal just decide to do it and get organised with everything you need to hand and attack it head on...would rather have had engine out and ski flipped over but hey we cant always have what we want....the tools you need are in my post i think
