The preload. We all know what we're on about even if you don't 
The torx bit on top of the LDA allows you to wind it out (anticlockwise) to further reduce off boost fuelling. It's that's been wound out all the way, and the preload on the spring (adjusted by the big cog type thing inside the housing) has been wound up too high (by winding the wheel anticlockwise) the pin will give less fuelling from its initial starting point, and be unable to drop down far enough under boost pressure to increase the fuelling because the spring has too much preload and/or the spring is going coilbound.
