EFI, Alpha-N vs Speed Density fueling Strategies

I think MAF is a better deal. I work with GM's factory systems every day, and the MAF system is much more forgiving for weather, elevation and engine combo changes. Different manifolds, headers, collectors, going to Denver, seldom require any tuning changes.

On many cars, (like mine) where would you put it? Going to put an air filter on it? The GM (don't know about Ford) sensors have heated wires. They glow red when running. They have to remain perfectly clean, or the calibration changes. Then you usually end up with elbows in the ducting to accommodate an air filter. You can't have dust, and who knows what else in Louisiana (Joke) cooked on those heated wires.
Speed Density done correctly compensates pretty well.
