Look around and you will find them. I have read them...and they have been discussed quite a bit.
FWIW, don't believe the "you can flash it back and no one will ever know" jazz...if they do the snapshot and send it off, you're screwed.
I don't doubt that GM can see a tune. I did a search and I didn't find one case of a Camaro being denied. Obviously it has happened, but they are few and far between. Oh, and I'm talking TUNE only. Not some guy who has poweradders that they can see is on the car. TUNE only, nothing else. I can't find one case of denial.
