I read somewhere that BMW USA was flashing the N54 ECUs with some weird tune which introduced more lag to add to the longevity of the HPFP, could this be the case here?
Yup. For N55's too. The SW update also includes some anti-tuner stuff too, besides the added "lag" tune. Basically, when you unlock the car... if you start to hear the LPFP (low pressure fuel pump) the car has that SW update. Early cars did not do that.
