So back to my first impression, power wise the car feels ok, it almost feel like my buddy's 335i /w JB4. It feels weird saying that, but I have nothing else to compare it with at elevation. Which brings me to this question. I have read that at sea level full bost hits around 17.5 ish, but stated in papers the M5 will do 20 to 22 full boost to compensate for elevation. But since I am still in my break in period maybe 20/22 full boost is not unlocked? I heard during the break in maintenance the dealer unlocks a few things in the car? I honestly don't know, purely speculative at this point...

The car will not perform well on the Moon, try coming down 5500 miles or so, things will improve.
