I found this very interesting.  When I turbocharged my Suzuki Samurai I lost
about 1 MPG.  I didn't calculate it as carefully as you did, though.  I use
the boost a LOT, because the car is so pitiful without it.  I do get a
little better mileage with Baby that you're showing pre-supercharger.  It
seems to do better when I'm having fun with it than it does on the highway.
I seldom drop below 30, and it's usually around 33. A couple of tanks have
been 36+!  Once or twice going steady 80 with the AC on it dropped to 28.
Maybe I'm not pushing it hard enough when we're having fun!  Everything is
stock except for the timing set at 14 BTDC.
