Curious - What would the dealer "see" different in the PCM if they were to hook the vehicle up to the TechII with a flash tuner installed in the PCM? Does the TechII tell them immediately that the current PCM program is not "stock" or has been altered?

How long does it take to reflash the entire PCM back to stock using the TechII? Is it longer than the 45 seconds it takes to return it to stock using the Predator?
