Looks like valves are operating properly. Was able to get a hold of Corsa last week. Based on the finding from the third shop, they are shipping one side of the exhaust to see if that cures the problem. If not, they think it is a weak OEM actuator. Corsa said exhaust should ship next week...

We installed the Corsa exhaust on our Blackwing back in December. Within a day or two the check engine light came on. We took it back to the shop which was unable to permanently clear the codes. Next, we went to a Cadillac dealership. They thought they found the fix by replacing a wiring...
