The regulator duty cycle map probably isn't so hard to recalibrate. It's mostly a function of the design of the valve and the pressures you put through it.
I'm fairly certain the standard regulator map will be good enough for ANY HP pump, assuming everything else is left alone... and by the same account, the map needs changing even with the same pump and same regulator if you want to run much higher rail pressures, as it's simply not set up for high rail pressures.
Thus we end up back at that point Ruan raised before any way, if your tuning that hard, get upgraded injectors, run the OEM rail pressure system maps/regulator (just with a high flow pump), and spend the money on a better turbo etc.
Pretty sure on the HDi the issue with hydraulic lifter failure is as much a function of trying to ram too much stuff down a small pipe = really high manifold pressures, as it is any design flaw set up for the OEM settings.
Anyone here having lifter issues with hybrids at high pressure? It always seems like people with standard turbos running them very hard, or just with parts in need of refurb etc?!
