Does anyone know how to initiate the over boost?
My understanding was it will be in the over boost status only for the first seven seconds after shifting with the gas pedal depressed all the way.

The pressure of the intake manifold of my 1M does not go above 1.2 bar (17.4 PSI) in the above situation. I can get 1.2 bar anytime when I depress the gas pedal.

It says in the manual that with the over boost function, it will get 0.8 bar (11.6 PSI) of boost. So my display should show 180kPa (1.8bar).
