I tune my CF with my left foot.And my right foot.
I'm a streeter, so it's a dump-it-and-go kinda deal. Can't get traction anyway in my neck of the woods.And it's seldom more than a gear and a half, so I hit the GV overdrive and call it done.7000 makes 66mph with 3.55s
Sometimes a little pedal in the corner wakes her right up.
