who gives a shit!! got to brunts and do a top speed run if you crack 160mph you have around 300hp or go the pod and do a 1/4 mile if you crack 115+ then you have about 300hp .rolling roads are a tool nothing more !! all i use one for is to see where my power and torque is make changes go back and see if i have a better power band and a better torque curve,not to see how manny hp i have .
