Old school speed density systems have computer controlled fuel injection - but they have a pre programmed MAP built in that does not change. But adding more air and better flowing exhaust will help.
Later model Mass Air Flow systems have many more inputs for the computer that change and compensate accordingly. These newer computers have MAP programs that "learn" the vehicle and adjust accordingly. Including more air, different fuel better exhaust etc.
Interesting indeed, thanks for the lesson. I was not aware of a self learning system for changes as stated. I know for my GT500 the CAI involved a pretty detailed tune in order for it to all work, thus where I got my knowledge base from. Funny that two short years ago this was required and now it is not.
