Also If the stock system flows more then enough air already, would it matter if some cylinders had more access to air then others if none are still getting less then they utilize? Which seems to be the case if larger TBs and bigger manifolds haven’t shown any gains.

There's more to tuning ITBs for gains with a modern engine that offers much more permutations in how the power is generated, compared to an old engine where you just go WOT for power.
can flow =/= does flow, just how a 80mm exhaust doesnt offer gains over a 63mm exhaust, on a stock car.
The unfortunate part of all this testing is that it's taking far longer than expected; it seems I will not have ITBs on my car for SLB this year
