Here you can see the spool-up of the 'Green'.  it hits 1.0bar at about 3100-3200 rpm.

 

 

Followed by the green hitting 2.0 bar at about 3750 rpm.

 

 

Here are some video segments from our tuning:

InCar2Bar2.mpg - Shot from inside the car, boost jumping up to about 2 bar, then back down to about 1.55 at redline.

InCarSlip21.mpg - Same shot from inside, but boost jumps to 2.1, and the wheels slip on the dyno.
