Hey guys so I pulled the ECU out of my 2011 3.8 coupe because I'm thinking about getting a flashed one and there's this weird blue marking on it that looks like BTR and I know they do reflashing for ECUs and I was just wondering if anyone knew if this is already a flashed ECU? Not sure why it would have it on their as I thought it was stock unless someone before me did it but I am not in contact with the previous owner. So if someone knows and could let me know if it has already been flashed or is stock that would be great! Thanks
