Hello!
On some 2L TFSI Cars, there is a 2550mbar Limit.
I cant get some ECU's to run in Open Loop Boost Control, specified target boost is much higher than 2550mabr (1,55 Bar).
As you can see in Picture, whenever boost goes higher than 2550, ecu reduces Boost Control Valve frequency to achieve always 2550.

Does somenone know how to fix the problem?

Its not on alle 2L Med9, i made many Cars with much higher boost than 2550.

No Problem to pay for a 100% Solution if somenone can help.

Best Regards
