It should certainly be open above 5/6 ish, and closed below that.

I belive the valve should be closed with the TPS connected, ignition on and engine off.

So is your "open" the same as my "open"? I am thinking that "open" means the power valves are recessed into the cylinder body, allowing maximum exhaust port.

thanks,
