Better mileage is going to be in your head, in your gearing, in your intake and your exhaust as much as it's going to be in the lean burn.
the VX tranny is going to give you better gearing then the HX even but your 1.6L engine most likely has a cam that is giving you lousy low end power and because of that running rich, to match low end power you need a tuned intake and exhaust that is matched to the engines lower speed.
