Stock Dyno Figures

I've read a couple of posts recently talking about the variances in the dyno numbers from stock 1M's. Perhaps quite a few people have taken baseline runs prior to modifications to gauge their power increase, but it appears the stock numbers significantly differ from the numbers provided by BMW.

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.
