It would appear the current pump and regulator can support up to 238HP; beyond that point, the fuel delivery is simply insufficient to accomodate additional power. Between 202 and 238, the injectors are working above a desired cycyle limit and will, among other things, get sloppy and overheat. They can keep up though in the dydno room during short bursts and can be tuned as well under these conditions. It is at the drag strip, though, that the limitations are seen and felt due to the continuous load placed on the fuel delivery sysytem. Bear in mind, though, that results can vary from bike to bike as a result of manufacturing tolerances and acceptable variations. While I have not done the math, the sizing of the present fuel rail and injectors is probably adequate; the big limitation is the pump and regulator. Upgrade to something that operates in the 50 psi range, both units, and it should solve the problem.
