What is the reason why the boost pressure of the EA888 does not reach the limit?

The boost pressure of the EA888 not reaching the limit may be due to turbocharger air leakage or damage. Car engine maintenance methods: 1. Maintain the three filters: The three filters refer to the air filter, oil filter, and fuel filter. The three filters play a filtering role for air, oil, and fuel in the car engine, thus protecting the engine and improving its working efficiency. 2. Keep the crankcase well-ventilated: Most gasoline engines are now equipped with a PCV valve (Positive Crankcase Ventilation), but pollutants from blow-by gas can deposit around the PCV valve, potentially clogging it. Therefore, it is necessary to regularly clean the pollutants around the PCV valve. 3. Regularly clean the crankcase: During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. Therefore, the crankcase should be cleaned regularly to maintain the cleanliness inside the engine.
