Doesn’t matter if they tell GM or not. You would have voided your warranty. GM would find it when the dealer submitted the PCM snapshot for warrant approval. It’s void either way.

Pass emissions

only problem is that might not turn out too well for cars with heads, cams or F.I..
The age of automotive performance is slowly becoming a thing of the past anyway at this point.

This may get you by an emissions check but this will void your warranty and GM will find out when the dealer submits the snapshot.
