I have installed a Stillen SC with a 9 PSI pulley and an upgrade 928 motorsports impeller and now the tuner is saying the car is running out of fuel above 6800-7000 RPMS, does anyone know off the top of their head what the 600cc injectors should be running at in this RPM range? I'm only hitting 440 at the wheels at about 7K when the injectors are at 100% duty cycle, is this normal?

I'm thinking I somehow mesed up the fuel pump install and just don't have enough pressure, is there a way to check fuel pressure on this car?
