Here is a screenshot of mine
the vehicle has had aftermarket injectors fitted 2 months ago but fuel economy worsened by 30 % when i expected it to "improve"
i was getting 1560 km per tank with deliberate lightfooted driving , with the new injectors i was getting 1100 km per tank under the same conditions .
( i have now got 31" tyres and suspension lift which brings range down to 960 km per tank )
anything obvious there to indicate a possible cause ?
MAF sensor has been cleaned , MAP filter has been flushed
