Actually, I don't think there is anything wrong with the way my WBX
vanagon is running, merely that by the time you figure in the weight of the
Syncro and camping gear, I am hauling a lot more weight up those hills. And
while the Digifant is a fiendishly clever system which, I'm sure, does adjust
the mixture properly for altitude, it can't make up for the change in air
density and the resultant power loss. The fringe benefit of higher altitude
is the reduction in air resistance at speed, but hills are still hills. The
only substitute for cubic inches that I know of is some kind of a blower --
unless it is to switch to a lighter version of the vanagon -- which I'm
considering.
