I tried to load the stock tune on an 05 lly yesterday, and it kept stopping with status unknown. The one time it finally got a good status, it stopped with bootloader rejected, and then a message: VIN indicates 97 camaro OS. I didn't try a full flash or a read, I will later, along with making sure the aftermarket head unit is really disabled. I just thought the camaro thing was weird. The worst part was after all this it wouldn't start, so I shat myself, then when I told the owner, he said " oh yeah the starter is messed up, you might need to tap on it." :what:
