I made a DSP5 tune for my buddy. It was my first attemp at one of these. Everything went greats and everything works great but ever since i reflashed the computer i keep getting a P0621 Generator 1 L-terminal circuit and a battery light? But everything shows that im getting 13.6 volts? I also keep getting( i cant remember the code) a driverside door ajar code? any reason? no problems until we uploaded the DSP5 tune. The tunes work great aside from this....
