For what you said to be true... these turbos need to be the size of rb's to make that power. Bmw wouldnt not choose turbos that large as they would not have the responsiveness worthy of an m car.

Thanks for your commentary. As stated, the +125whp tuned power "quote" also takes into consideration better fuel and a Turbo Back Exhaust. On the new m3, it is no far stretch to assume a TBE will net +25whp, and better fuel...another +35whp (with tune). That is +60whp or so, of my original total number of a tuned +125whp...that being said, we have a remaining window of 65whp to be had with a tune, outside of fuel and a turbo back...given the tuning window BMW provides as a standard with their engines now-a-days, that 65whp or so is not a far stretch, at all.
Instead of nitpicking each others numbers which are relatively accurate, you should just be happy you will own a +600hp tuned M3 at some point in the future. I don't know about you, but that definitely excites me.
