My intentions are to remove the VATS when I get the PCM flashed with the VIN. Unfortunately, I am past my budget at this time and this project is taking place now, where I have the resources and facilities to do it. Then.. I will need to drive back home, a few states away. Another detail I need to investigate is the Impala being a California Emissions car with the auxiliary AIR Pump and related components.

IF... This equipment remained pinned to the new PCM, will it function? Does the mainboard of the PCM have the ability to operate this equipment pre-manufactured at the hardware level? If so, are they P&P functional or would this need to be addressed with the PCM flash?

I am very grateful for your replies on this topic BTW... There are many small details that must be thoroughly investigated as I do not wish to fight the battle of tending to any issues that could have been taken care of easier and faster with the car in its current dismantled state.
