What OS is it?

I've got a tune for a 2003 5.3-A4 Avalanche here that I was "playing" with for someone. This has a 12579405 OS.

any chance i can look at it?

I've "dusted it off" and checked it over. The txmsn cal has enough well proven mods to it for a better feel and the two timing tables are conservative and safe.
