    Yes, the coils are constant lives one side, R9 through the inertia switch and pump relay through R9's contact and they are both supposed to get earth to the coil on the other pin from the ECU once the ignition is turned on so the ECU doesnt do...

    On a second thought...as long as the pump doesnt start on ignition that's the path to be investigated, ... it means that the relay is missing the trigger signal, it must get positive feed from R9 and earth from the engine ECU so remove the pump...

    That's how it was conceived for SLS operation and maybe those who engineered it didnt think to make it as to be disabled once the vehicle is set to coils or the SLABS didnt save the coil setting only the BCU so double check the setting in SLABS...

    I didnt measure the SLABS wake up drain but that's normal to be higher untill it goes to sleep but it should go to sleep after 30 minutes(or max 90) even if you leave the door open... Do you have air suspension?

    Maybe things got worst in time cos based on the actual MAP reading it's obvious that it instantly goes to overboost so the lack of power is normal for that default

    So that's definitely a big problem, now unplug the MAP sensor and read that way, eventually drive test it with sensor unplugged.... as you replaced the sensor seems that it's a wiring issue on that path or the ECU has a fault

    Be aware that if you bought complete pipes untill the block you need new seals(RVW100010) and plastic collars(ANR6700) under the bracket, some sellers say they are for air suspension which is wrong, the old ones are not reusable
