    [QUOTE=Bidja;739006]bigguwesty - Read your message when I got home last night from a drive up the mnts. Some long hauls and limp came into the picture big time.. Heaps of adjustments latter to get it as good as I could by staying above 18psi. Ended up 19psi max and cruise 12psi - slight load (handled limp OK but sluggish when revs were down and loaded up). EGT reaching 500 degC when moving out and working. Easy hwy driving performs good but not right for me..

    On way home was thinking of removing needle... Before removing needle will attempt further adjustment method as:

    So imo close the needle valve, set max boost (rev out to 3500rpm for max boost)
    Once your happy then open the needle untill the turbo arm just floats off the adjustment screw..
    This should give you a 2-3 psi drop while cruzing../QUOTE]

    What max boost (15psi)?

    By the way, with only tillix what is your setup?
    Youll find that 15-16 is the max the ecu will allow on hills etc.
    Itll last for a bit but once that time limit is reached and the fuel cant be matched itll throw to limp and kill the fuel input..
    So imo wind back to 16 see how it goes, with the needle valve shut.
    The crd doesnt limp with quick spool up so you wont have issues with fast spool up.
    If it goes into limp still at 16 psi drop back to 15psi.
    Im at 15 max and can do the adleiade hills in 5th no issues now.
    Tbh i noticed no loss of power going from 18 to 15psi as there was no fuel to match it..

    Once your happy with a max boost level that isnt limping then crack open the needle valve to reduce your cruzing boost a bit.

    My setup is yea needle less now.
    My car is a lard ass lol weighing in at 3t daily.
    So i found that for the needle to have any effect it had to be open so much that ut made take off laggy as hell..
    So with a max of 15psi its at max when cruzing at 100kmh i get 13lph.
    Im hapoy with that..
    Drop to 90 it drops to 14 psi and if i drop to 80kmh it drops to 12psi..
    Cheers
