Fuel requirement is based on RPM x LOAD.
A dymanic range of 2x will only over 3500-7000 RPM at the same boost pressure. Most WIA system injects between two fixed pressure settings. If you include that variation in the calcutation, you need a dymanic range of may be 3x? Let say 2.5x, making the dynamic pressure span of 40 psi to 250psi. Not many pumps can do that.
I could be wrong, but on paper, the pressure related system can only cover a small operating range.
