I thought with the latest release (2.24.817) the V6 G8 was supported?

When I tried to read the ECM/PCM the other day I got several warnings (including a "service dealer warning") and was unable to read. I can get the exact warnings if they're helpful.
Any thoughts? I tried to search but haven't found much on tuning the V6 G8 around here.
Car is a stock Pontiac G8 V6
