If the old WBX is in good shape and well tuned, the only thing negative that one would experience with going to altitude is simply some reduction of hore power purely and simply due the change in air density. The higher you go, the less dense the air, the richer the fuel air mixture will become. But the Digijet and Digifant injection systems operating as they do, they will compensate for the changing air density, by reducing the amount of fuel bringing the fuel/air mix ack into balance for the best burn. Of course with less oxygen in the less dense air, not as much power will be developed. But probably the power loss is not significant enough to cause one to have to pull off the road.
