Hi all :thumb: We have a tag axle motorhome 2.8 jtd 2007 (old shape) which has been chipped. We use the van mostly on long motorway runs, so you would think conditions are quite similar but I get quite different mpg figures, between 13 and 27 mpg, all be it the 13 mpg was through the depths of devon on twisty twiney roads and steep inclines. Usually it wont go below 19 on motorways but can be as high as 27. I would of expected it to do 27 mpg on motorway runs, do you think something is playing up like an air flow meter or am I barking up the wrong tree?
Thanks in advance
Paul
