D5196 can be changed, but it won't have the anticipated results for upshifting.

Do all your LLY defuel refinements in the ECM torque and fuel tables.

I think we just leave it to B0744, it seems like the operation of the defuel can't be changed but instead you just use B0744 to correct the defuel that was thrown off by changing the pulsewidth from stock.

Although I can't figure out some of the cells in the stock tables. For example where in the upper torque values it goes from 85-90mm3 to 106mm3 just going from 3200-3400rpm? Im tempted to try the stock B0744 table on a 3000us tune.
