Charging pressure right??

When unpacking, I noticed that the AutoGauge is not at zero, but at about -0.2. Installation soweeit everything worked well. Then, on the first drive on a free country road I tried a little bit. And the LDA shows me the following values: Idle: -0,9 Bar Take away gas while driving: -1 Bar (or even more, display only goes to -1 Bar!) Fully Accelerate: approx. 1,2 Bar And jetz If I fully accelerate at approx. 70 km/h in 5th gear, the display goes back to up to 1.4 bar and only after a few moments to a constant 1.2 – 1.3 bar. If I see this correctly I have to calculate in about the -0.2 bar, which is missing up to zero position, right? That would be with what I have read so far too high values?? Unfortunately did not find in the search about the max. loading pressures or also the serial values. Hope one of you can give me there we iter help if I should contact my chipper again… Greetings, Lox
