Currently sitting at 19L/100, but generally around 20-21L/100. Car is mainly driven to work and back in peak hour traffic, but the way I drive I don't think it should be that high. It has come down slightly since being tuned. Luckily I only have to fill up once a fortnight as I don't clock to many km's.Anything I should check/replace to help with this? o2 sensor?

Its all changed. The fuel usage is measured from a constant.. that is.. the injector being the original sized factory unit. If you change it it will be flowing more but the ECU is still trying to work out the fuel used going off the original injector. They work it out using the pulse width and so on.Pre-tune my FG was averaging 10.5-12.. mix city/hwy and the odd squirtPost tune with 1000,s its sitting on 13.8-14.5.Doing a full tank to KM comparison doesnt reflect the increased usage its telling me. And rightly so.. a good tune shouldnt give u a higher fuel usage. That is if it isnt running the correct AFR's on and off boost Link to comment https://www.fordxr6turbo.com/forum/topic/43910-fuel-consumption-merged-topic/page/131/#findComment-1321759 Share on other sites More sharing options...
Bellato Donating Members 2,713 Member For: 14y 6m 9d Posted 07/11/12 02:04 AM Share Posted 07/11/12 02:04 AM Exactly what Jimmi said! Don't use the trip computer and actually see how many kms you get out of how many litres of fuel and work it out manually. I found mine was quite off. Also discount your battery and it will reset your trip. When I did this it reset to almost spot on to what I was actually getting Link to comment https://www.fordxr6turbo.com/forum/topic/43910-fuel-consumption-merged-topic/page/131/#findComment-1321766 Share on other sites More sharing options...

From memory it seems to be getting similar km and litres when filling up, hopefully my memory is wrong haha.
