I'm one of those guys that likes to do everything myself, but sometimes help from someone who really knows what they are doing makes all the difference. Les obviously knows what he is doing! I'm really excited with the progress that has been made, and to get everything dialed in.
    Ive read your PM..I'll be addressing your questions/concerns this evening.

    Glad you enjoy the tune.

    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.
