K14 'turned up' 12 psi before.... 10 after :/

Ideally you want an air line and to plug each end of the inlet system and see if it holds air. If you're not on an FMIC though that won't be easy.

Could be a knackered actuator spring and the wastegate is just flapping about. Did you feel the wastegate arm tighten up at all when you turned the allen key?

A little bit dude, still on topmount, could it be overfueling? Although apart from smokey it was fibe at 12 psi :/
