How to Solve the Lack of Power in Cruze?

[ArthurMarie]

From the turbocharger body to the throttle body, all turbo pipes and clamp connections are normal without detachment; the throttle body sealing gasket is also intact and well-sealed. The intake port shows no obvious oil traces, and the exhaust port turbo has no significant play and is dry, indicating the turbocharger itself is functioning normally; the air recirculation valve is also well-sealed. When experiencing insufficient power, it was found that the intake pressure value and the average actual boost pressure are about 10-20I0PA lower than those of normal vehicles.
