Verified the timing: It was correct.
Now i am going to reinstall everything and do more test.
Unfortunately i cannot find the compressor maps for TD04L-13T, only the TD04H are.
The customer choosed this turbo because in Europe It seems to be widely used. It seems like everybody gets their 240 bhp. Unlucky us i guess, back to tests.

 

I've read that the H, L, and HL all refer to the turbine side. The compressor map for a 13T compressor wheel should be for all 13T equipped turbos.

 

The google machine finds a compressor map for a 13T, looks like a smaller trim gt2554 to me, which means it will probably hit sooner and run out of gas earlier.

The dyno above seems right in the ball-park. This turbo is also clearly targeted for higher boost applications.
