That's a fair point. although the 18 PSI is an absolute max (over all temps and altitudes). So say nominally its closer to 14 PSI (complete guess) then couple that with the new tech/methods BMW is using to improve lag/responsiveness (new Mitsubishi turbos, Impulse charging, Flow-enhanced manifolds, Electric wastegate actuator) and maybe the disparity goes away.
One things for sure though, I'm definitely excited to hear some first hand accounts in a few months (hopefully).
