Missing power 2.0 JTS engine

Hello Alfistis, drive an Alfa GT with 2.0 JTS engine mileage 5000km. Wanted to know what the engine brings and drove to the performance test bench of the Bosch company the whole twice. The surprise was corresponding. 105 and 107 kW were measured once. But that is not enough. The power curve does not run linearly but constantly regulates. At the engine all basic settings were checked. Without success. At the technology center of Alfa in Heilbronn it was then called the Mot I have now opened another Alfisti. with the same engine that drove with his vehicle to the test bench. Running power over 15,000km. Result – same performance values and up and down regulating power curve. After a further request by the authorized dealer at Alfa in Heilbronn at the technology center, a technician informed that this would allow the rolling software to operate here. Rarely so laughed. For how bl I can only say, up to the test, this one smells like rotten eggs. Does Alfa have a spawn here in the basement???
