Have another question to the specialists: I did the Hirsch Step1 for my 2.0T 210PS MJ08. After the installation of a trailer coupling in a Saab service workshop the extra power was suddenly gone again. The switching points of the automatic are shifted upwards and the murderous torque from 2000 rpm away. The executive mechanic probably didn’t know too much about the Tech2 (the specialist was on vacation). Therefore he tried around the AHK for a long time to program n. Among other things, he has had to re-enter the performance data, transmission type, tyre sizes etc. (I was standing next to it). After the finding of the missing performance by me and a corresponding complaint was checked again in Tech2 and according to statements of the workshop the software version is still the corresponding of Hirsch-Performance. Now my question: Is it possible that the software level of Hirsch is displayed, but the actual parameters by the intervention again Because power and torque are definitely gone, the top speed is about 220-225 km/h.
