New to Mercedes tuning, coming from diesels a little different. Im looking for some Input on a amg gt file that was pulled, and also any help with getting some more burble at lower rpms.

I don't have that eng but I kinda know based on knowing my engine. Also note I've never done it, I have zero interest in alerting the cops to my presence, or annoying my neighbors.
For mine it's apparently done by retarding the spark at decel.
So I edited what I assume would do what you want, the blue cells from 2k on up at 9% load. Then on the other chart you can see they set the Min Spark really high to avoid anything like that from happening, so I'd assume you have to make that negative as well. I assume the further neg you go the more noise it makes, so maybe start at -10?
I think, and remember I know little, that some program in more fuel in this same zone. Mine cuts fuel way down in that zone so maybe it wasn't loud enough for some?

Here's one I found from another member that did it. I see no fuel changes but his tune was apparently mostly done by some other tuner not using HP, so there could be stuff we can't see.
But fyi, pretty much what I remembered:

Two questions:
One; which engine model exactly? If it's am M178, and it looks like it, I believe someone was asking for an oem read of that. So let us know if 178 and for sure unmodded?
Second; you named the file "RED AMG GT READ FILE". Is that because you have so many of that particular car you use colors to differentiate them? I do the same with my Lambos

It is the m178, this was the file read from the car it is modded I’m not sure what all was adjusted, I have a VR file from our alientech I’m going to see if I can somewhat compare. And also have a 2021 white amg gt 63. I will also be doing a little tuning on a buddys yellow amg gts
You win. I just have the one car, plus my old truck.
I can't tell much from your tune since I/we still aren't sure what oem looks like, but one obvious thing was the Normalized Torque is 472 instead of 885. Not sure what that would do, if maybe it would screw something up? I've also never seen anyone do that. Maybe someone who knows can chime in?
Mine is lowered to 800, which helped. I also I tried as low as 750 but anything <800 was no better, so 800 it is.
