I'm wondering if anyone knows why? It consistently shows up that the 1M should have 335/340HP depending on where you read it, but some members are doing stock runs pulling near to 380HP.

Could this be a low number given by BMW, or a difference in the types and calibrations of dyno machines. I'd love to have my stock stripper dyno'ed, but I don't know of any close by.

It's winter here and my M is covered up in the garage until spring, so I find myself over anaylizing.
