There's a tunable TSFC number that you can play with.  The engine
model isn't smart enough to vary fuel consumption with condition (real
engines have variable TSFC's under different situations).  But as long
as the number used is correct for cruise there shouldn't be too much
difference over a long flight.

You could also check the throttle setting in the cruise parameters.  I
think I have most of them at 100% right now (max speed numbers, as
opposed to cruise numbers), lowering that should lower overall drag
and improve cruise-regime fuel consumption.  As always, the best
numbers to use are ones from a POH, if anyone has them.
