If no fault shows then my next move would be to give the boost solenoid a clean and check all reletive pipework

0.9bar is just over the max of the standard ecu anyway.
Fuel cut is more of a 'head through the windscreen' rather than judder.
Normally fuel cut happens in the colder weather (or so i've found).

did you ever find the cause of this? I'm having similar issues with my twin turbo legacy following head gasket replacement...
