I don't get how less power and more consumption go together unless there is new resistance in the equation somewhere - like severe wheel alignment issue. (Rear toe-in? Always driving up an constant incline both ways to school in a snow storm...?)
Barring that it sounds like fuel quality (lower energy), or a mucked up IP - squirting at the wrong time. Does it knock? Blow grey smoke?
You say refreshed timing chain... did they get the timing right?

I follow your thoughts, but can assure the wheel alignment is correct, and there is nothing holding the car back.
I had a garage change the chain. I usually do most work my self, but not this one. They did adjust it, and I can only trust they did it correctly.
I must assure the timing is correct, but is that a guarantee the IP is delivering fuel at the correct point? If fuel delivery is a little to late, I suppose it would influence power at the higher RPMs the most, correct? Can this be tested in any way?
It does not knock, rather the other way round, people say it knocks very little. The sound is as smooth as only a MB inline six cylinder can be.
