I'm not sure about this - unless the Barracuda operates differently from other pumps, the ability to restrict the outlet does reduce flow, but that isn't linked to power draw - reducing the output/flow typically increases the back pressure on a pump but I'm not sure that it reduces power useage.

Power draw will reduce slightly as head pressure increases, this is typical for most centrifugal style pumps.

You can see in the spec sheet how the power drops.
