Engine Light Eliminator

Check engine light using chips?
I was wondering if buying a SCT Mustang 4-Bank Eliminator Chip for my 2000 Mustang V6 auto will make a check engine light come on or not? I've heard that adding a chip will automatically make the "check engine" light come on and might hurt the engine/trans. Please help.
chips are a waste of money unless you can certify it is for off-road use only
