Ok, to some reason you are hitting exh temp control and cyl pr. limit but not sure this will trigger vct to disable.

Other then that it might not be where you command it - cant see a tune to tell. Both banks are close so in position.

Not sure by any means but it hitting Cylinder Pressure limit may very well be contributing to that issue. I noticed when tuning my S197 any time I hit any limiter (torque trunc, cyl pressure) the car would not go into PE. I'd recommend maxxing that table out.
