Would it be fair to suggest that if this is included in the official empeg software, that it should only be enabled when the empeg is in the car, and disabled if in a home environment?

At least it should be configurable to be enabled/disabled separately for home/car use. If I understand it correctly (from posts here and from the link Tony posted to the explanation of dynamic compression) then having the volume adjustment permanently enabled in both home and car environments is not necessarily ideal.
