The Clipboard says that the B29 manifolds and rpm for max cruise are in the image attached.
however with the new settings of the throttle / rpm you cannot set them to the max cruise settings
when you reduce to 2200 RPM it reduces manifold pressure to 30 inches and you cannot adjust manifold.
This is a Bug, same with the B17, its not a supercharger issue, it is related to the VR Throttle Code that was introduced for people moving their throttle instead of the RPM
