Think of this in terms of optimal cylinder filling -- too much restriction is no good, too much flow is no good. It's gotta be just right.

That said, adding a mechanical "choke" is almost definitely less desirable than adjusting valve overlap.
This makes sense.

The problem I am having here is that no one has mapped a setup on this engine like this in the UK before. TDI who mapped it are VERY good but this setup I feel requires specific knowledge of the engine. I couldnt have asked any more of TDI, they went above and beyond on the day

I have sent Motion Lab a PM to see if they would be happy to remote in when the car is on the dyno to alter/tweak the map. Hopefully they will get back soon.

Can anyone else recommend someone who might be willing to do this?
