Boost Target vs Actual: Read the Shape
How to compare requested and measured boost while keeping pressure, temperature, and calibration caveats in view.
Look at the relationship

Separate finding from cause
A tracking difference is a finding. Its cause may involve airflow, control, leaks, heat, calibration, or measurement quality and needs verification.
