Its just a matter of ecu tuning in my case. ecu tries to get more boost even its not capaple to deliver so it injects more fuel. The Turbos vnt control is not fully in use due to program is for smaller turbo whichs boost peaked a lot so its not closing totally the vanes in current program.

There are 3 "programs" in depending on my gas pedal position.
0-70% is at the moment very efficient but no boost is the 2 liter fuel consumption range. 70-90% is efficient acceleration with 0.8-1 bar boost
90-100% is flat out acceleration (all in) with 1.5-1.7 bar boost

at the moment the car goes on to that 90-100% range on bigger uphills and gives smoke.
