What happens with your injection quantity above 2600rpm? It drops from 89mm3 to 80mm3 instantly?!? That must be quite noticeable drop in torque...
Also your turbo control could use some tuning... It over-boosts over 3bar quite badly. You are requesting too much boost in lower revs. Requesting too much boost in low revs (below 2200rpm) always ends up in big over-boost.
Anyway your question was about power. If you didn't alter the injection duration maps in a "bad way" and the 80mm3/inj is "real" number. Then my bet is 180HP. And around 380Nm below 2500rpm.
But there is quite some reserve left if you ask me. In the area between 2600 and 3500rpm you are running with AFR above 20:1. You could drop that close to 17:1 quite easily and still have very low amount of smoke.
If you will succeed in raising that IQ then you could be close to 200HP with 90mm3 @ 4000rpm. And probably around 450Nm @2500-3500rpm with 100mm3/inj.
