I did a log with the car just idling and two 3rd gear pulls (you'll know which is 3rd gear when you see the hp go up. I went all the way to redline) and this is what I came up with.
The idle log is called "unhackedmaf"
The first run "yes" was on zeroed fuel.
The second run "yes2" was on lowered fuel.

Notice that the car knocks more when fuel is lowered. What the hell???? :confused: I don't get it:( .................

What turbo you running, how much boost, which injectors and fuel pump and finally, do you have an adjustable fpr?
You should get a wideband. I recently got one and it makes tuning with dsmlink even easier. I found out that these cars like to run around 11.1 afr on pump. Maybe your global is too low and already puts you leaner than you want to be. So taking fuel out just makes it worse. I would add fuel from 5500 up (using the zeroed out fuel settings map).
 
I second what he said, add some fuel to the 5500+ sliders and try again.

What boost pressure are you running? Your boostest is only in the 12psi range. I think you are running into issues with your mas not seeing airflow like it should be. Boostest should = actual boost, if it isnt you will run like poop.
