Need Schooled on MAP, IAT, and Stoich

I thought I'd resurrect this thread with some MAP questions.

After a few hundred miles of observing the MAP figure on the SG, of course decel = lower numbers and higher FE, and accel = higher numbers, lower FE. Just brainstorming, it is possible reduce the manifold pressure at higher RPMs, and still maintain stoich? I'm not sure how you would do that without increased vacuum or some such.

...or is MAP a result of what is happening, and cannot be manipulated unless forced induction is added to increase the figure, and negate FE gains?

...just brainstorming engine functions...
