Technically, disabling & deleting the EGR Valve are two slightly different things.
To disable the EGR Valve in the .bin:

You can raise the 'CAT Protect Min Coolant Temp'. Anything over 120°C should do fine.

GM uses the following values for vehicles that were never equipped with catalytic converters:

Min Coolant Temp for CAT Protect = 150°C
CAT OverTemp Threshold (Low Baro) = 1065°C

5. DISABLE AIRpump
Besides clicking OFF at least two switches / flags, you must ALSO raise the Min Coolant Temp to Enable AIRpump to well over 117.5°C / 243.5°F.
