Adding EGR?

[4pointslow]

I need an EGR system for a LS swap I am planning.
So far my specs are
12200411 PCM
5.3 LM7
Drive by cable
4L60e
4x4


I think I am looking for a bin file for preferably OS 12212156 that has an EGR system monitor in it.
The BIN files I have obtained like the 2002 Chevrolet Silverado Truck Auto LM7 5.3L (12212156) look like they don't have the monitor. (even with the egr system being changed to "enabled", using Tuner pro)
Let me try to explain,
I am using an Autel AL-319(can also use OBD Link software) to see if the monitors are there, they show as not ready or not available.
If they are not available, it seems as though the PCM with that OS doesn't have that monitor.
If they are not ready the monitor seems to be there but just not run yet (of course).

Only BIN I have found with EGR monitor in it has been for a different operating system (2000 CHEVROLET SILVERADO (OS 12205612) that doesn't have a known good XDF file to support it.
It did prove to me that the Autel AL-319 will show the monitor as not ready if it is in there and enabled.

Am I going about this wrong? I do see 1999-2002 Chevy truck (IE Suburban) engines with egr systems on them, on EBay so I know they exist.
