It is doing about 20L/100km around town driving fairly sensibly and about 15 on the highway. I realise they are bad on fuel but it has definately gotten worse than it was.Only other mod is generic 10psi flash that has been on the car for over a year. The car is running smooth and has no issues, just slurping more juice..... Thoughts ?

Bin it and get a NTK one.And then get custom tune.

Just out of interest though is there any chance the extra air intake could be contributing as well?

Am planning on custom tune, but want to be sure everything is right though. The reason I mentioned the extra air intake is because when u increase airflow on imports they generally get poorer fuel consumtion. Saying that these things run map sensors as opposed to maf, and I am not as knowledgable with map sensors and how they work exactly Link to comment https://www.fordxr6turbo.com/forum/topic/78950-fuel-consumption-after-cia-and-02sensor-change/#findComment-1197387 Share on other sites More sharing options...

I put 1 from bursons spares and after 2 weeks soot everywhere on the back of the car. Went with the NTK and fixed.

I think the 2 brands used by ford are NTK and Delphi.

Oh well! The new NTK is on the way so all should be good.....Thanks again!
