            Not much turbo pressure with n75 connected (0,5 bar), so assumed fault code has impact on that (but not sure)

              It could be connector getting brittle with age you can solder another one to current wiring ....

                But the RS2 timing is meant to be 1/2 or 1 tooth out from the factory marks. Do some searching here and you will find this info. Well known.

                If you have your N75 Waste Gate Frequency Valve (WGFV) electrically connected and all you are getting is spring pressure boost (0.5 bar) then there is an issue with the pressure connection between the intake manifold and the Manifold Absolute Pressure (MAP) sensor in the ECU or the MAP sensor has a problem.

                    The RS2 cam sprocket and G40 Shutter wheel is a 105B (the ABY and AAN is just 105). The B is marked on the shutter wheel.

                    Here are some details about the 105B:
