So, it seems the nozzles definitely have a higher flow rate.
I also took some new K-Power measurements, covering the same route there and back.

The injectors installed are Firad DSLA142P1025, and according to Dieselsend and my research, these are the correct injectors for my engine.
Can someone shed some light on this?

Okay, I'm not upset about it. It accelerates really well. The slightest bit of smoke is only visible in the second gear at high RPMs under full load, and only in the rearview mirror.
