So we have our 200 Nm target and we have, via wastegate control, a throttle inlet pressure that is higher than our requested manifold pressure. We call the difference between TIP and MAP the “Throttle Plate Delta Pressure” and this intentionally generated pressure difference is what makes the modern control system work.

The ECU is now able to control the inlet manifold pressure by regulating the amount of airflow allowed to pass through the throttle blade from the intake system. Having a little more air pressure in the intake system than the manifold gives us an instantly available reserve of pressurised air and thus instantaneous throttle response when needed. Let me try and put that into a couple of scenarios.
