I'm not crazy about stretched bikes. I think extensions are a dangerous shortcut, and I don't want to spend a grand on an arm and still spend 400 on a progressive controller. With a megasquirt, I can get the tune dialed in, build in traction control, and have progressive nitrous control as well as a launch limiter for the same price, and not give up anything in the corners. Why wouldn't I want switchable, tuneable traction control, nitrous or otherwise?
