Sounds like you’re getting active misfires. The rest of those crazy codes can pop up on an LT4 under misfire conditions. My brother has a Z06 and when he had a bad plug wire he got the Service Rear Axle error too lol. I see you have headers…I’d definitely check all of your plugs and wires. I’d bet money at least one wire got toasted on the headers…
