This discussion started with me telling a list member to contact drag
racing sites for an altimeter.
AA Fuel and Funny Car racers that use NITROMETHANE use altimeters to
select a pill for their injectors. A chart comes with the altimeter that
has a list of pill #s and at what altitude to use them for different
brands of injector pumps in combination with different brands of
injectors.

The carts aren't very accurate but It will most times get you through
qualifying until you can make your own decisions.
