Hello guys, I bought such a tuning box around 199,- Euro, which supposedly promises 27hp and 42Nm more power, as well as the further advantage that PS/Nm can be adjusted by means of adjustment wheel, in order to be able to minimize the power a little while with too strong Russbildung! But the instruction is very spartan I have the following problem, on the note only says above: “Box between the plug of the rail pressure sensor hang” I read everything in the manual, but there is never anything of a rail Druchsensors described, respectively mentioned where this is located! Maybe someone can help me here, where the thing comes to? Thank you
