Installed a maggy 2300 on l83 yesterday. They supply an mpvi2 device. Was able to get the tune from them and the rtd driver software also. All went well except for when I try to flash the file. It just says unlicensed vehicle and sits there. I had licensed the vehicle with my mpvi2 and got the trifecta tune out and flashed everything back to stock before installation. Reaynced the rtd tool. Shoes credits added, just sits there at unlicensed vehicle and does not bring up the credit selection screen. Anybody dealt with this issue or have the base L83 maggy file handy? Customer wants to keep their tune for now for warranty purposes.
