Those logs you sent me have most of it but...>
Actual boost at the Manifold on the VAG is a calculated number (not real) based on MAF flow. The command is requested boost, the IC is actual boost measured downstream at the MAP sensor in front of the battery.
True manifold levels can only be measured with a gauge as there are certain things happening within the manifold via valve timing, reversion etc. that result in higher numbers than the IC levels would indicate.
