From what they say here driving small turbodiesel around 1500-1700 RPM leads to clogged turbo, clogged EGR and who knows what. When I was at the inspection responsible technician was revving up my engine to clear the soot emissions and advised me not to drive like I did. So now I drive a bit below 2000 rpm, accelerate quick enough to get in speed soon and than try to stay in lean burn. Using this I am able to be in par with NEDC figures, or even beat it.
