I am definitely on board for updates and new information on this. From your dyno charts it looks like you trade power below 4500 for top end power, do you see this smoothing out for those of us with daily drivers?

You have to understand that the OE manufactures put tons of money into fuel economy and emissions not power density which is what we are after. By all performance standards the FA20 is a joke, in the 70's you could buy a 260whp naturally aspirated 2 liter 4 cylinder engine that ran on pump gas. In 45 years manufactures haven't forgotten how to do that, they just cater to the masses. Your average person buys based on mpg. On top of that they have to meet strict emissions standards. That's where the money is spent.
I can't say I know what you mean for "do you see this smoothing out for those of us with daily drivers"
If you mean can it be corrected with tuning or something along those lines than to be perfectly honest no, it definitely can't. The DI system has a definite advantage at low RPM and medium to high load. This could be fixed with a built motor but that's another story all together.
