Would need to read the properties from the PCM. And ideally, you'd want to read the entire PCM to BIN from your vehicle to serve as the base for tuning (and a backup in case you need to go back 100% OEM.)

My 2004 Tahoe L59 came with 12587603 (which has extensive xdf and considered a good donor) but I updated it to 12606960 for a couple enhancements. There's a WIP XDF for that, too.
