All 89 5.0 Mustangs came with Mass Air from the factory. They used an A9L for a 5 speed and an A9P for automatic. I think the California cars had an A9S. All of these are Mass Air computers. If you have some other computer, someone has altered the car.

depends on what you want to do.

Speed Density = exact specifications(doesn't like altitude changes very much)

Mass-Air = Tolerates Changes in almost everything.

If your good with a speed density setup in terms of programming, then go for it, definitely good for specifics. But for the normal bolt on and go scene, Mass-Air is the best IMHO for the benefit of plug and play compatibility.
