Does anybody here have a Jet Chip installed on their new mustang???? I thought I read that some people here do. I do and I have a question.

When I installed my Jet Chip, everything seem to work fine, I drove it for a half an hour, no lights on the dash came on, etc... the car ran great. Went to bed and the next morning after driving for 2 minutes or so, my emission system light came on, what does that mean????
