Thanks for sharing, it sounds like similar issue I am having. I have 1050x injectors with radium surge tank too same as you. Stillen A2A SC

The mechanics working on my car installed 2 fuel pressure gauges, one at the line and one after the rail. Pressure is good at the line but falls after the fitting on the rail.

I have forwarded them this post so hopefully it'll help them out.

You are still using OEM rails? I was told these needed to be upgraded to fix the issue however upon researching, most other supercharged cars around 500hp are still running OEM rails perfectly fine.
