• Is this a mechanical gauge?
  No, this is an electronic gauge, even the versions with the sensor mounted
  inside the gauge.
  
  
• How exactly does the bi-directional bargraph work?
  Since there is a need to clearly distinguish between vacuum (negative
  pressure) and boost (positive pressure), the gauge shows these two
  states as different directions on the bargraph. For vacuum, the bargraph
  starts on the right and grows to the left for increasing vacuum (decreasing
  pressure), and vice-versa for boost. In operation, as the intake pressure
  level increases, the bargraph gets smaller (towards the right),
  representing less vacuum, until the pressure level becomes positive. At
  that point, the bargraph switches over to start from the left and grow to
  the right, representing increasing boost pressure. This also effectively
  doubles the bargraph resolution.
