CAMARO6 - View Single Post - Which performance mods will not void warrantee??

I had some issues that led to the ECM being bad, I only had a CAI and catch can as mods. The service manager has always been good about mods and said as long as I haven't tuned it I should be fine. When the question of a bad ECM came up the first thing he asked me is if I have done a tune. He said he would have to flash the ECM and send it to GM, and if it showed a tune he said they would most likely deny warranty. There doesn't seem to be a standard rule as far as warranty but it seems many use the tune as the line to cross.
