I was getting 27 MPG before supercharging. I now get...27 MPG! I have even gotten 33 MPG on the highway during club tours, with the supercharger.
Why? Well I was always in 3rd gear, stock. I am now in 5th all the time. Also I'm not in the boost every minute the car is running. Maybe only 25% of the time (...well more like 30%...).
The only comment I can make about fuel requirements is the local octane is too low. To really get the most from my supercharger I need a little octane booster.
