Mein Farfignueggen is that maybe GDI intake valves and ports accumulating excessive carbon deposits in ports and back of valves could restrict expected flow and cause the boost pressure to become higher and waste gate to be needed sooner than expected under hi load? I would think it would have some type of random misfire on warm up besides if carbon on valves is an issue though -
