i could be wrong, but the only gas saving turbo engines i know of are diesel ones. for petrol motors, once the turbo starts to spool, it pushes more air into the engine while the injector duty cycle increases to compensates. so it wouldn't really make sense that it can help save gas
if your boost is below 0psi, it's the same as running a the motor NA. IMO, the turbo would be extra weight that you don't want use if you want to get better mpg
to increase your mpg, i would recommend starting by hooking up a boost/vacuum gauge, and try to keep the vacuum around 10 inHg. after I did that on my civic vx (d15b motor), my FE went from 38 to 42 mpg
