    Mine boosts to 0.6/07.bar (holding) and overboosts to 0.8/0.9bar, when the ignition is off does the needle sit at 0 or is it slightly under 0?

    Right so the gauge is out like mine so you more likely boosting to 0.6bar which is normal m8, what does it overboost to?

    Over boost is where ther car will temp boost abit higher than normal, mine does it if I'm sitting at 2.5prm then put my foot down only for a sec though then drops back to normal, think its to help with overtaking.

    Think it should be more like 8.7psi, well thats what 0.6bar in psi is anyway, is your gauge in bar or psi?

    Should be a slight vacuum (under 0) when throttle isn't at all open if I remember right.
