Adjustable Fuel Pressure module

Hi. Has anyone fitted one of those fuel pressure relief valves on the fuel rail on a A1 ZX12R. I have an A1 currently producing 200bhp at the wheel and 101ft/lbs of torque at 7000rpm but still running stock ignition advance. I advanced it 6 degrees but when it was on the dyno the operator said it was causing an issue at 9000rpm. This was later found to be the fuel pump issue so I am currently building a hi flow pump and filter for. I'm aiming for 225bhp at the wheel.
