X-Trail 2,2 dCi / performance development

Hello X-Trail driver, have a little problem with my 2.2 dCi (T30) , EZ 06/2004, and hope you can give me some advice with your experience. I got angry with the bad performance from the beginning, even though the new model has 100 kW (on paper). Had just the same model as a workshop replacement car and I was really baffled, he went off like Schmitz’ cat, who got a real boost at about 2300 rpm. Then with the factory The workshop says it may be that the model has already changed a bit, since the replacement car was EZ 11/04, but I can’t imagine it, so the difference in the performance was so sharp, my speeded up, as if no turbocharger was installed. Who drives the same gear? I would like to hear some opinions before I show up at Nissan again or should I have a performance test (motor test stand)? Greeting from Berlin Seppelnase
