I was looking at the stage 1 super kaos kit. They said that it includes everything including new fuel pump and regulator. He said that it will take the power up to 260hp on a stock motor. It is 4300$ I would like to know you guys opinions on this set up and about some other kits if you like them better (including price and if everything is included). I have heard of the hahn, what do you guys think about that one??
