It can help ... but not always. Its a bit much to get into right now, but basically you're a lot more likely to find improved fuel economy with aftermarket kits than with OEM blown engines. I'm not positive but I think that whether the or not an engine will see a gain with supercharging is based largely on the compression ratio.
