Good analysis though.

That is not a equal comparison.
A smaller blower pulley forces more into the motor by spinning it faster making more power. The boost level is just a restriction in airflow. Obviously the larger cam flows more air, and will reduce the restriction in airflow, thus a lower boost reading on the gauge. But when you added the smaller pulley to achieve the same amount of boost, you added more airflow by spinning the blower faster, and of course it will make more power. Put the original blower pulley back on the blower with the larger camshaft. Yes your boost pressure will drop due to less airflow restriction, however the blower is still forcing the same amount of air into the motor as it was with the original cam you started out with. That will be a equal comparison.
