High System Pressure & Low Control Pressure Balance ?

Another WUR mystery, I would love some feed back on this, , 930/66 euro fuel head , spec are

SP 6.0 to 6.7 bar
The WUR 112 specs

CCP 2.2 bar @ 35 deg C
WCP 3.65 bar +-0.2
BCP 2.9 bar +-0.2

And this what I got, 930/66 stock good flowing head ( flowing just over 300 mil per min @ WOT at the 009 injector)

SP 7.4 bar (way to high)
CCP 1.0 bar @ 23 deg C ( seems Normal )
WCP 2.3 bar ( to low)
BCP 1.8 bar ( to low )

She drove great, fwhp 420 and 490 torque at 4,200 rpm's, lean on top , geart low & mid range power, why is the low CP's working with such high SP ? is it a good thing ?

My theory is that the SP is so high that it leans out the system that was designed to work at a lower pressure , combined with high SP and Low CP's on the WUR that balanced each other out.

Is this possible?
