Do Over... CIS Pressures

After I got him started and running fine, he resorted back to his old ways. Here are the pressures with the 930 spec pumps installed...
Ambient Temp 84F/27C
System Pressure 6 Bar (88PSI)
Cold Control Pressure 3.5 Bar (50PSI)
Warm Control Pressure 4.65 Bar (68PSI)

It seems like the WUR is doing its job by raising the control pressure by 1 Bar from cold to hot. Is there another spot where fuel flow could be limited, thereby increasing the pressure well beyond the spec?

I cleaned the plunger and blew air through the return line... everything seems okay but these pressures are completely wrong.

As always, any and all help is appreciated!!!
