Interesting stuff:
At the same stock boost pressure, it runs a lot higher wastegate DC% than the n54 which peaks out at around 35% in similar conditions. This suggests that the wastegate spring is softer, the wastegate solenoid bleed smaller, the turbocharger has less capacity or a combination of the three.
For comparison, this Wastegate DC% curve in a n54 would yield around 12-13psi.
