    Sounds like you pretty much got it mate.
    If anything i would wind in the needle valve a tad more. This will rise the 100kph boost just a little more. At 18psi max i would want to see around 12psi at 100ks. But if your happy with how it is then leave it.
    In time you will understand more how it all works and tou can really fine tune it and hit that sweet spot full on.
    Who needs a dyno when you can do a few road runs and work it out yourself.

    Yeah thanks heaps for the info. Ill leave it how it is for a bit and see how it goes on hills and stuff. Having it spool quicker, will this keep the egt down a bit better?

    Thanks for the info Mudski.
    There aren't many Patrol owners over here, even less with NADS mods.
    It's good to have re-assuring base line readings.
    It's interesting how closely related boost and EGTs are too.

    It will help with the EGT's but not a lot. A better/ larger scoop and better intercooler would help with EGTS more.

    This thread was a great read, questions followed by answers that was easy to understand. So many different versions in Dawes and needle valves but this helps out a lot especially if you don't know what your doing. Cheers guys

    not sure which thread to post to, but I was not satisfied with the original install of the Dawes and needle, as I found the trade-off between spool-up and max boost to get a continuous and nice boost curve, not quite I was expecting it.
    So I modified Chaz's schematic as follows to make the best use of the variable geometry of our VNT :
