Is your FPR Working? 442 WHP should not be needing 90% duty cycle. Hopefully you figure that out, but it sounds like maybe your fuel pressure is not raising at a 1:1 ratio.
I spoke with Eugene and he said:

It was checked. The duty cycle is around low 80s at 6200 RPM on e75. And with very reasonable fuel target. The increase in duty was also linear.
