Few questions..
is that dyno at the wheels or crank?
what year is your car and who’s tune?
the torque is really high but the HP number If at the wheels is about what you see with dyno of stock w212.

2015 e63S
Tuner is out of the Germany, McChipDKR
I did a baseline stock run and it only put down 477awhp and 523awtq...

Your dyno is showing SAE correction, which is about 2.5% lower than STD from a dyno of mine that I just looked at. So that baseline 477 SAE would end up as 489 STD, and the tuned 567 SAE would be about 581 STD. So that's a little bump, for when you compare to what others will tell you of their AWD E63 baseline runs.

Few things that may be happening here:
Your peak delta from stock to tuned is about 90whp, so thats pretty strong gain. But the top end power really drops off. Almost 100whp loss from 5K rpm to
6K rpm.
Looks like they are, like many tuners on this platform, throwing alot of boost at the motor esp down low, and possibly some bad boost control going on.
As mentioned, huge spike of tq, and that high boost either tapering off so aggressively from timing being pulled and boost, because of high IAt’s.
hard to say for sure without boost numbers, a datalog, and more details.. this tune needs some refining for sure.

Can you share a dyno plot showing pre and post tune?
As mentioned above this looks like someone's thrown gobs of torque at you, with your top end suffering as a result.
On my earlier tunes i saw this loss of horsepower up top as well. My latest tune shows great gains in the top end, with my trap speeds at 129 mph now, up from 120 mph.
I'm a 2014 E63S running Eurocharged's latest E60 flex tune. My torque is maxed at 760 awtq to help minimize clutch slip, while I'm at 670 awhp now.
Notice how the power doesn't drop off like previous tunes did.
Also note this is made at 18 psi... the car is much happier now.
