    SDV8 boost pressure

    Around 200kpa raw from the gap tool, on just a quick push up to 60kph... not really trying, havent had this function enabled before.
    Another noob question, 2 turbo's so a small then a larger? So this reading is inlet manifold pressure? or big turbo wastegate pressure?
    As always, all comments welcome, though ones that teach would be betterer... Hey Ron !

    more uninteresting stuff..
    sits around 175kpa fully loaded at 100kph on the flat.
    It reached 245, still fully loaded, overtaking another van.

    no point asking about uphills,, there are no hills in WA...
    I have really liked WA.. but by god its a lot of nothing....

    The VVT primary is the larger and the fixed secondary the smaller.
    The readings would most likely be directly from the MAP sensor, being total boost.

    Something different,have you ever checked the “charge air” temperature,which is air entering engine,compared with air entering airbox,which is generally close to ambient.
    This will give an idea of intercooler efficiency.
