ITBs as an eco mod?

So I was watching YouTube videos about cars (passing time) and I came across a video from Engineering Explained where Jason goes into pros and cons of individual throttle bodies, one of which he said was reduced pumping losses due to not having to pull a vacuum on as large of a “container” with ITBs versus an intake manifold and plenum. Is that to say that properly sized ITBs can increase the efficiency of an engine? Assuming that the rest of the air intake is similar and there’s a plenum above the throttle bodies?
