I'm not sure how true that is...I know for a fact that for a Duramax truck, any drivetrain warranty work must be preceded by a screen capture of the calibration #s from the tech II (showing vehicle vin#) before GM will approve the warranty. And, my buddy (service manager @ local dealer) says the newer vehicles use some kind of global diagnostic software/scanner that is online, so GM is automatically linked to the car/ecm. They've basically taken it out of the hands of the dealers...and you can bet your butt that if GM cares about the tune on some farmer's diesel truck, they're gonna care about the tune on that your new SS Camaro!
