There are many Controllers within the C7 system that can be updated, basically for each VIN the Calibration history needs to be checked via TIS to determine the software level, actually GM assignes a part number to each software update by system/subsystem. As an example Controller K71 is the Transmission Control Module Programming (Auto) and 5 part numbers relative to the subsystems.
So the answer to your question is you need to have the dealer verify your software based on configuration. Yes, Z51 should be different due to eLSD and in most cases MSRC.
