By Ultimate TBI do you mean the new ROM code that RBob came up with?
That code isn't compatible with any stock mask, so getting a baseline
for that will be difficult unless you can find someone else using it
that has an engine similar to yours, and has done all the tuning.

Good news is that UTBI includes fast datalogging and WB support, so
tuning it shouldn't be too difficult.
