I don't think that the loss of resolution in the vacuum rows between
turbo and na has much to do with it.
I noticed when I was na last year, that it's very easy to get near
100kpa with small throttle applications at lower rpm. With the Link's
2D AFR targets, that puts you at "WOT" O2 targets when you are just
puttering around town.
With they Hydra, or another ECU have has 3D AFR targets, you could just
set the entire lower RPM range at a lean target, and then richen it up
as the RPMs rise and you start to make some power.
If I were setting my car up for economy na, I'd reset all of the AFR
targets leaner, reduce accel fuel. I would guess that for street
driving, you could get by with setting zone 6 at just slightly richer
than 14.7, zone 1 at 14.7, and go leaner on the rest of them. There may
be something to be gained by playing with the timing map, but it'd be
hard butt-dyno tune in at such low power levels.
I get better fuel economy with the turbo compared to na partially
because I've got zone 2 tuned to 15.5 or so AFR, and zone 3 (100kpa)
target at 14.7. Boost rows are richer, obviously. When na, I had zone
6 (95kpa) tuned to 13.2 for good power... and I was in that zone a lot
in just regular driving around.

I was putting my foot in it too much with the turbo... And now that
I'm N/A, I am STILL putting my foot in it too much.
One question I posed that has not been addressed:
Assuming I keep my boost gauge to the left of the "0", would putting
the turbo back on the car net any economy increase from the added
volumetric efficiency, or, would the added weight and loss of
resolution between N/A mode and Turbo mode on the link balance that
out? Is there any real benefit?

I'll take a leap here and suggest Keith was just saying properly tuned
large injectors will get the same mileage as smaller ones.

Not irrelevant at all. The original poster was very concerned about
putting his foot into it...

That's irrelevant. You're still delivering the same amount of
fuel, you're just taking longer to do it with a smaller injector.

If you have the 440 or 550 CC/min injectors, you COULD
swap them out with something smaller...
