what did you expect? check out http://www.holdencrazy.com/EFILive/stockTunes.php there are plenty year "2000" cars using pcm os 09381344

I'd recommend updating to a 2002 OS. 12225074 was used by HOlden/HSV from late 2001 onward (till the 1MB PCM anyway).

If you do swap to a 2002 OS. 12225074 (which is a good idea as it gets rid of the backup VE table and you also gain lean cruise) just remember to change B4001 injector flow rate to match the original tune.
