Hello Greg,
OS 12593058 is an updated 2003 truck OS (typically used OS 12579405). I don't have one for a 5.3 L / 4L60. If you check the Tune File Depot site, there is a tune with that OS for a 2003 GMC Yukon LQ4 / 4L60 - you would have to adapt the engine portion of the tune to suit a 5.3 L.
Regards,
Taz
