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.
I'm also very curious, but coming from scientific side, I hope they do a proper analysis eliminating other variables (or at least accounting for them).
They are showing 5% increase in power across at peak which is HUGE for just changing the fuel injectors, and they show almost 20% increase at 3350rpm and >10% up to higher rpm where it drops off... .... To me that gives a red light that the difference doesn't come from what they state (6 injectors, 6 runners vs 4 injectors for 6 runners)
notice, this image is from the same post.. if this is used for comparison than the discussion is in completely different direction... Having injection on to the PP port having fuel cooling the apex seal will reduce drag and improve sealing ...
