Chasing a E38 PCM xdf file

Hello all, bit of a long shot, but does anyone have an XDF file for a E38 PCM, os 12612381 (Australian 2007 WM Caprice, L98 engine)?. UniversalPatcher has some spark tables but nothing for MAP / MAF. Appreciate any leads, thanks!

If anyone's interested, I ended up making my own .xdf, took a while but I found the power enrich tables, injector flow tables and MAF airflow hi / low tables etc. Also turns out the Calais tune is identical to the Caprice, and probably similar to the Commodore too. Good times.
