so is 320hp / 330 lb-ft all we're going to see out of a "tuned" n55? that seems to be showing up in the 640i, this ///M135i, and the performance pack on the lci x6.
that would be disappointing, because that is less than the N54 tunes with the 335is, z4is and the 1 series M. they all had that crazy overboost 379 lb-ft thing.
