So.. School me on fuel management..

I'm a newb in building force induction vehicles, but I stumble upon an "Almost" ready force induction Mazda3, yes, a regular 3 being Turbo'd.. It looked good and everything seem to be up to spec so I got it off the previous owner.

When I first got it, it had some issues with CEL coming on, plugged it into the OBD2 it read first cylinder not firing properly or not firing at all, so I replaced that ignition coil thingy. After that the major problem comes in, the car doesnt seem to be easy on gas. I understand when boosting, you tend to loose fuel economy, but what if a full tank at approximately 45L per fill up I can only get as far as 300kms, and thats very close to empty the tank.

This is a 2006 Mazda3, the previous owner is running about 0.5 bar boost, very light, and using GReddy E-Manage Ultimate to run the fuel maps. I was told that the E-manage isnt a quick enough fuel management system for these cars, and I do plan on moving to AEM FIC6 to get a better tune, but damn, is there a possibility I can get a slightly better fuel economy in the mean time?

a bit more info:

Driving Habit: light throttle, ususally in Drive. (I know, manual swap coming in soon, no factory manual models in Taiwan)
Fuel Octane: 98 equivalent to 94 in Canada/US
Exaust temperature sits at about 200 degree on Defi gauge under normal city driving, highway driving it sits around 5-600 at around 130km/h
Boost: hitting 0.3 bar boost ususally once - twice a day. (I dont redline every light)

If there are any more info needed, I'll provide them as well..
any experience on GReddy E-Manage Ultimate on newer vehicles?
