… thinking about STOCK intake manifold and its pressure in time running

- the higher the restriction in the Y (MAP-sensor-position), the higher the pressure delta between Y and the imf
- the restriction in the Y in stock version is high, when only one cylinder is fed - and relatively low, when 2 are fed
- when a inlet valve opens (the restriction decreases instantly), the pressure in the imf peaks for a moment
- when a inlet valve closes – the opposite happens
