    Hey guys,

    To my knowledge the boost gauge in a 944 Turbo S shows a value of slightly under 1 bar (center of the gauge) when you start the engine but are completely off-throttle (~0.95 bar; the gauge is meant to show absolute pressure, not only relative pressure above atmosphere).
    When going on-throttle it goes to the right, adding at least 0.7bar boost pressure, and when going off-throttle, the the closed throttle intake valve creates a vacuum on the intake manifold (where the engine is still demanding the same amount of air intake) and thus the gauge shows values below 1 bar (needle to the left of the gauge).

    Getting the off-throttle gauge behavior right is probably an unreasonable ask for a dev team, but it's max value is never over 1 bar is very wrong imo and should be fixed.
