Jeff,
There aren't any special changes that were made to your tunes when they shipped. You may need to have the PCM scanned for codes as there isn't anything that I can think of that would cause the CEL to come on immediately on start-up short of insufficiently cleaned PCM contacts or a hard failure of a sensor or something (wierd that it would have happened overnight though).
