Fuel usage roughly per 100km ?

[XR6-VCT-2000]

Hi guys , I was just wondering what the fuel ratio is roughly supposed to be for an standard auII xr6 vct ? . I thought i read somewhere about it being somewhere around 12ltrs/100km to 16ltrs/100km ?.

I haven't had a chance to take it for a run yet on a long trip, so i don't really know what it's like economy wise on long trips , but around town im lucky to get 70km from 14ltrs latelly ($20 worth of premium unleaded). ?

I remember when i first got the car the economy was ok/nb , then i added 2 extra CIA intakes to the airbox and a small scoop for the snorkle , the economy improved and so did performance slightly when planting the foot... then i inserted a k&n filter and switched the transmission to power mode , huge imrovement in throttle response when booting it ....but - latelly i have just been cruising around in power mode #1 and it still seems to be sucking heaps of fuel ?, i havent bothered checking the map sensor yet as the car runs hard as , no problems with performance/idle/temp or anything , just sucking heaps of fuel i think . ?

I havent reset the ecu since doing any changes, im thinking of trying it just to see if there's any improvement , not that it really bothers me too much , but any saving is better than none ;) .
