I've heard the same about the tune for the 2019. Kind of surprised GM doesn't just update our cars at the next service interval.
I'll ask next time I take it in for the oil change.
What I have found out is that the ECM wasn't touched during the repairs, but they would have disconnected the battery while the SDM and sensors were being replaced. So I believe this may have reset the fuel trims and it's relearned my driving?
Either way, it's now much closer to the SS than ever before from a stop and it's a lot more fun to drive.
