No I don't expect this. Full air is just for starting. Non-cats burn best when the air is turned down. This makes the draft pull air through the secondary. If it was at a single high burn rate a lot of heat and emissions would be heading up the flue. What's being tested now are automated controls that sense several parameters to determine the stage of burn and adjust the controls accordingly. This is an early work in progress.
Burning clean, and burning efficiently can be two different things. Full throttle might mean low opacity and complete combustion, but isn't very efficient with 950F chimney temperatures and high flow rates up the chimney. You need to slow the flue gases down so the heat can be exchanged out in the stove before it goes blasting up the chimney.
That would be a major redesign. The TN20 is a decent heater, but with much less costly innards. It's a tube stove without the stainless floating firebox design or linked secondary air control. The EPA emissions listing is 1.8 g/hr for the LE
