how much power can a 040 support?

my car is running out of fuel at 7000 rpm on the dyno... adding more fuel in the injector table isnt solving it. injectors are 6X600cc injectors and running pump fuel. im not near the limits of the injectors IMO.

6x600cc = 3600cc/min = 3.6L/min of fuel when the injectors are fully on. An 040 supports 102 L/hr @6.5Bar and 12V = 1.7L/min so if your fuel pressure on boost is say 4bar you can expect at least (6.5/4)^(1/2) x 1.7L/min = 2.1L/min maybe more if the fuel pump voltage is 13.5V. So an 040 is good for about 400 engine hp @BSFC = 0.55.
