This tool can show the pressure differentials in the port without the valve in place. This has been a longtime back room test, to show the efficiency of the port and if any changes made are in the right direction with respect to the valve in place.

Ideally if the air flow through the port is greater with the valve in place than with no valve at all, any change made is in the right direction (learn now to move air around the valve, you can't move air through the valve). Generally if the port moves a lot of air with the valve removed, it is not an efficient port, so test that way and learn even more about your designs.
