I take it the CP3 is fitted with an appropriate relief valve that operates on a duty cycle type map?
Assuming it is as that is what makes sense, then again that would be easy enough to make work with a few days tinkering.
All these things are good ideas, but as I was getting at earlier, it's REALLY important they are done in isolation, possibly even at standard power/mappings where you are guaranteed good calibration of all the maps against each other, then you can tune that control map for the relief valve perfectly, put a line under it, and call it a job done.
Mapping gets much easier down the line then if you can say for certain that the control map is right and you can just apply it to any CP3 modded car, because you took the time to get it perfect under perfect isolated conditions. A good reason why pioneer users should do things slowly to help the person doing the mapping out, even if they are doing the mapping DIY it'd be very sensible to isolate a pump no one has used before as the only mod and get it right
If you plan on running big injectors then tweaking the relief valve mappings beyond the standard ~ 1500bar is pointless as you won't want to go that high anyway, so that also makes life easy within the 'range' of the standard EDC15C2 mappings for the HDi90 (ie, many maps end at 1350-1500bar range)
Only problem then is extending IQ range out and duration calibration maps... a big task no doubt, but one you could get through if you work sensibly through checking at each point via PP2000 and OBD logging etc.
