In my garage the valve was closed un-started, I fired up the car, put a flashlight up to the left side and the left tailpipe where the valve is on that side and it was closed. Again I started in park in my garage valved was closed. I turned on M mode when I started no valve opened. So I assume that the valves open possibly at a certain RPM when being drive. Anyone have a thought on this?
