From the multiple 03-04 vehicle and 04.5-07 vehicle tuning I have done there is no conversion needed. 12.5% on a 03/04 is the same as a late CR.
Now, the part that is confusing is the 12.5% on UDC is not quite the same as the 12.5% in UDC, it's close but not exact. The ECM has a little more variance in it, and the tables are not as linear. This is common from 03-07 and has nothing to do with the 65% limit on 03/04.
A 03/04 will pull from the 80% cell, but it will be stuck on ~65% for display purposes. ~65% is NOT the same as 100%.
The single best way to confirm it is rail pressure vs rpms, of course both have to be stable.
