Despite what some people say/think there is no such thing as an economy map. The economy is controlled by 'YOUR RIGHT FOOT'.
When driving around off boost or very light boost the ECU will run stoich mixture and attempt to achieve a perfect burn of 14.7AFR. The ECU will run this regardless of boost settings/targets in the map or overall top end fuelling/power levels.
The only way to be more economical is to run less boost, but if your hitting any more then 0.8bar boost your not driving very economically anyway.
Best bet as the guys above have said is to run a good map and a poor fuel map i.e set it to run on 95RON.
