After installing some new mods I went on a 214 km test run in 10C air temp, windy, with some light rain,at speeds between 100km/hr and 120km/h, [62mph and 75mph] and got a disapointing 3.8L/100km [62mpg]
I suspect that it had to do with the low teperature and the relativly high humidity both of which affect air density. I will have to make more test runs to see... and look into what relative humidity does to air density.
