Gregs: The laws of physics are the same, but EFI can use the capabilities a little bit better. On my dyno I tuned radical race motors with carburetors and produced good power. After those engines were converted to a smart EFI system I made about the same max power but I was able to tame the idle a bit using the above techniques with no cam change. In a race motor you design the cam for the engine/head combo and then tune as required.
A wide LSA cam is a way for an EFI system that cannot do these things to run better on the street simply because idle is better. Its not much more complicated than that.
