If you use higher-flowing injectors you will actually want to lower your stock fuel pressure from the 3.0 bar to keep from running rich at low throttle. To see what I mean add the larger injectors and keep the 3.0 bar FPR, drive the car for awhile then pull the spark plugs. You'll notice carbon on them.
But if I lower the fuel pressure how is this a benefit you say? This is where the rising-rate fpr benefits you. I'm running a 2.8 bar regulator with SD red injectors and a rising-rate regulator. No bogging at low throttle and plenty of fuel for the higher boost levels.
