I ignore the MAF I stick a full tank run it dry them work it out 
yep started clocking the miles last sunday and now kind of have a figure,
its done 55miles on £15 and sitting on the edge of the red box on the gauge coming home
last night.
what do you think?
i was thinking i could of run a lambo on that and still have change

to add this was without the big boot and taking it easy..
