Why would it need reloading unless something had overwritten it? The 1M, 335is and Z4 sDrive35is all have a performance tuned version of the N54, this is just BMW doing the same with the N55. It could be a different engine variant like the 6 series uses, but we won't know until someone takes delivery.
