Mazda changed from 2 injectors in the primary port plus 1 in the secondary to 1 (larger) in each port with slightly finer spray patterns. I don't think that changed the power output in any way. Smallish differences in injector size and spray pattern , from what I've seen for myself and observed from others, seem to be relatively inconsequential.
What TB are trying to demonstrate is that having injectors in every port is better for power than leaving any port injector free. Sounds like they are going to do some in depth analysis of this ....I await with interest.
