I did recently replace the valve cover AND short PCV pipe with OEM, VC was slightly leaking oil, was hoping maybe it'd fix any air leaks too if they existed.

As for the turbo diverter valve, the feeling of this stutter/hesitation is very sharp, like a misfire feeling. I think turbo pressure issues would be more gradual, like a sine wave sweep vs a sawtooth (what I feel).
