I have to say that's a bit disappointing. Midrange hp/tq is already huge on m157, that's where the engine shines. What is it that makes it so hard to gain any more power at higher rpm after tune and catless dp on this engine?

Am I reading this right? You already had a catless downpipe and swapped for the turbo back downpipe? If so that is pretty significant.

It's significant but not much more whp even in midrange.

I guess a turbo upgrade is the only way to get stronger on top end. Amg loves small turbos
