That way you can test it "chipped", and know what will happen if it fails. I'd bet it will pass, since you haven't noticed much smoke.
A good service writer at the Ford dealer may be able to get it flashed for free, as you weren't the one who programmed it.
Good luck.
p.s. make sure to put in a new air filter right before testing it, and run the hell out of it the day before.
