Is this stage 2 an optional upgrade or the new base map being offered? Any reason why the description you posted up top still has the "old" numbers? I would like to see the new dyno graph when available. Has this ever been run against a stock X5M? If so, how does it compare? Motor Trend lists the X5M at 10.4s 0-100mph...
