quick question... say ur driving and you want to change from closed to open how can you tell if the valves are completely open or not ? it seems like you need to hold the button down till its open and the light stays red and doesnt change to another color to inform you that its fully open. is there an auto mode also? where say the valves open at a certain rpm.
great system and youe car looks gr8
