Vauxhall Turbo E55 ecu Missing parameters

I have a file from a remote customer that wants to get this vehicle tuned but it seems it is missing a lot of parameters and wondering if anyone has dealt with this platform before.

The boost is controlled via the ECU and has internal wastegate and electric solenoid to keep things in control but, in the file itself, there doesn't seem to have any tables regarding boost or wastegate control?

The customer is also complaining about overboost codes and from the diagnostics, it looks as if a few parameters could be added to stop this from happening. There are no max boost, PR, airflow tables to adjust either.
