Real world performance differences--Velos Tune on X5 50i

I got my X5 back a couple of weeks ago from the N63 service work. My Velos tune was cleared, I assume due to the fuel injector calibration sequence.

While I wait for Velos to rework their magic on the new stock map I extracted earlier in the week, the current state provided a nice opportunity to do some 0-60 runs in stock from, and compare to the 0-60 runs I did just a few days before the car went in for the service. Most enviornmentals were the same, same--same location, roughly the same temp/humidity:

The specs:

2013 X5 50i (base)
Wheels/Tires: 18" 210's, Michelin Latitude Alpin, 255-55-18 (non-runflat)
Ambient temps: Mid-Teens (F), low humidity

The measure:

P3Cars Vidi (on-board, fed from vehicle's speedo feed)

The setup/launch:

Traction control disabled
Shifter in S (auto shift)
Brake torque to about 2500 RPM, release brakes, floor throttle

The results (0-60):

Velos Tune (best): 4.68
Stock (best): 5.50
