I know this is an old thread, but just an update after reading it a few months back.
I gathered 5 flow sheets from various injector companies, and compared them to stock flow numbers from 2 others... Best I can tell is that the rapid drop of pressure at short/low duration (like at idle) led me to increase pilot under a certain pressure... leave it alone in the mid range, and reduce it high pressure.
Seems to have worked in keeping the engine quiet like non-upgraded trucks.
