AMG_Comeon

Hoping someone can help me here. I have a 2021 AMG GTR, had it since new, and last week I took it in for its regular service.

When I picked it up, I RIGHT AWAY noticed it quieter... Then when I drove it, it was like I was driving a different car. Everything is quieter, less pops, everything.

What do I do? I drove it right back and they said they didn't do any software updates or anything.

I took the service guy for a drive and he said he notices it a bit quieter...

I know this has been an issue for some c63 and GT folks, but wow this is just terrible.

Is there a fix? (without a tune and all that)...
