Stutter at Idle - ALPINA B7

[TxGR8White]

Trying to chase down a slight "blip" in the idle when I am stopped at a light. Engine has new injectors, fuel pump, fuel filters & FPR. Timing is spot on and knock sensors, O2 sensors VVT Solenoids and valvetronic motors are all okay. Car won't stall, but it just isn't "normal" and is starting to get on my nerves - it almost sounds like a very aggressive cam is installed. Any help would be appreciated.


Thanks in advance.

A recalibration of the eccentric shaft and valve travel did the trick.

I thought that happened every time you turn on the ignition? or at least turn it on without starting the car.
