In the past we have found that a supercharger can lose a pound of boost or so because of the decrease in back pressure.
Losing a pound of boost doesn't necessarily mean any power is lost. A supercharger at a given rpm will put out more cfm at a lower boost pressure. If back pressure is reduced by use of low restriction exhaust components, then one would expect more air to enter the engine. More air along with appropriate amounts of fuel should yield more horsepower.
