Here's some data for you guys. Another forum member and I went out last night and did some vbox runs.
My stock 2012 X6M did the 1/4 in 13.5sec (one month ago, same test road)
Velos tuned got me a best of 12.83,
Velos tune and Velos Downpipes with race cats, ran a best of 4.37 0-60 and 12.56 in the 1/4 last night.
2013 X5M - Velos tuned, Akro full exhaust,
12.68 1/4 (stock downpipes) and 4.45sec 0-60
Keep in mind this is in 3300ft elevation, but DA is closer to 5000ft equivalent. The thin air really hurts the power here. I make 100whp more at sea level in a car that puts down 1010whp here. (Calgary AB)
Cheers

Both Vbox screen captures are from my run.
