Cool video.
Emissions regs are the chief reason why OEs tend to be quite modest in terms of tuning. You're selling cars for a global market- so your IAT comp tables have to be just as happy in Southern China as they are in Northern Canada. If BMW suffers a motor failure because they tuned too aggressively for a single car, that's a loss they'll likely have to foot. Not in their best interests to get that extra degree of advance, or whatever it is in question.
