The motivation for many to MS their car is because once you push the turbo boost out of the realm of the reasonable, the stock computers (even Turbo computers) can't react adequately. Combined with radical changes to the hardware of the motor, mostly injectors a lot larger than original (to keep up with the increased air volume going into the motor).

For a reasonably stock normally aspirated motor, the advantages gained by going to MS are much smaller. The stock fuel systems (even carbs) just weren't *that* bad at doing their jobs. Of course, you can add O2 sensor feedback (wide or narrow band), add intricately configurable fuel and spark maps. But all in all, you are talking about incremental gains in HP and efficiency, assuming you do a good job of tuning.
