Problems with the Ecu tunning - cayenne turbo s 957

I recently Have an ecu tunning. I have send it to UK for the tunning and when i receive the ecu i had problems. The car (cayenne turbo s 957) was prepared and taken for a test drive, after 100meters approximately from the garage the engine cut off and PSM light and engine light came on. We returned to the garage to check everything and the fault codes stored in the control unit and the fault code: “ P1552-Function Monitoring Control unit Fault Group A signal Implausible”. We followed guided fault finding and the outcome was that the control unit Is faulty.It looks like it is a software problem because the car runs fine at idle and before the turbo kicks in. As soon as the turbo kicks in the problems described occur.

Please advice

Thank you
