Yep we tried a temp tune with heaps of timing pulled, didn't make a difference.

MAF sensor has been cleaned. Will try and find a replacement for testing.

Non Cruise timing has no KCA until 1.10 load, then adds 5.6. Cruise adds 5.6 from 0.36 load... so I think the effective timing is a bit closer matched between the tables.

Cruise AVCS/Timing is not active when it does it(as per logs) and the interpolation timer between Cruise and Non cruise would make it a non issue. It is not a sudden 'map switch'

Tried a temporary tune with the wastegate zero'd out... (to rule out solenoid noise). No change :(
