But are you sure about constant pressure valves ? I was told they leak some pressure to cut peak injection pressure when cam is at its fastest point. So with normal delivery valves you might get a little bit more fuel and higher peak pressures. I had big marine nozzles with H pump and it was hazing at idle. No different from P pump. Pop pressures were set to 300 bar.
Timing at idle was 4 degrees and at 1600 rpm 13 degrees, without load. It was Euro2 emission though, so retarded timing.

What did you use to control the pump?
