Has anyone replaced injectors on the B9 3.0TFSI / EA839 engine?

I have a persistent misfire on Cylinder 1. It only occurs at moderate or wide open throttle, higher boost situations.

I have new plugs and coils. It runs fine at idle or light throttle. Problem occurs on Stock, Stage 1 - 91 and Stage 2 - 91 and E85 files, seems to get progressively worse with additional power output with respected files.

034 did some logging on it and determined fuel pressure is meeting the requested values and the car seems otherwise healthy.

Doesn't seem to have excessive gas in the oil. Oil looks clean and normal, no indication of coolant. Coolant level is stable and appears normal.

Front O2 sensor was replaced about 2k miles ago.

The fact that it only occurs under heavy throttle leads me to believe the injector is likely clogged. I would like to swap it out with a new injector, however I have never pulled injectors on a direct injection engine. Not afraid to dive into it, just was hopeful someone else had done it previously.

Tips, tricks, info would be very helpful.

Thanks guys!
