I have not ventured into using PCM Hammer or TunerPro for OBD2. I use EFI Live and TunerCats OBD2 software / hardware for PCM flashing / tuning.

Maybe some parameter enable / disable basics will help:
Minimum speed to "enable" set to 255 MPH could be used to Turn Off something like EGR.
Minimum temperature to "enable" set to 151 Celsius could be used to Turn Off something like the EGR.

Error codes can be tricky, because not every operating system is the same.
No Error Reporting should disable an error, like the codes for the rear O2's
No MIL doesn't necessarily stop reporting the error, most times No MIL will keep the computer "Thinking" about what to do with that parameter / function.
MIL on first error - is usually needed for vital functions like ignition and fuel parameters.
MIL on second - is usually needed for emission parameters like Charcoal Canister Purge (CCP).
