no, it is a package
You could do all of this without the intake charge contamination, by simply using less throttle. The gain in combustion efficiency far outweighs the minuscule increase in throttling suction.
i disagree with what is above
and so do the facts
it is not just suction throttling loss , which effect is much greater than the value you attribute to it.
it is the whole package
use of EGR at cruise reduces fuel consumption and emissions
that is the fact
no way around it
