I did a read entire on the original tune and tried to send it back down but it didn't work. I got a new OEM ECU and had the local GM dealer download the GMPP tune into the car and all is good now. It's a 2007 car with over 100K so the old ECU must have been near the end. Anyways learning all I can, and appreciate all the help on the forum.
