On the LLY, there isn't any single table. Combo of throttle inj, main injection, base torque tables. I see you have an LLY, but asking about LBZ. LBZ defueling can be caused from a number of different things. TCM is one, fuel pressure tables can be another.

As Rob stated, you have to adjust shift defuel in the TCM for an LBZ. There is another way, but it involves fully rewriting the tune around the TCM torque commands. It's an ugly mess.
