You mean like to decrease pumping losses? With my very limited knowledge about that, I would think that this kind of slight improvement on intake side could be canceled because of a bit higher resistance on exhaust side. Maybe?

But as you say, boost equals more oxygen equals more fuel to burn, so it could be the situation that any modification that increases power needs longer gear ratios to make any good for fuel economy. With boosted air you don't have to open throttle that much to maintain certain speed, but the amount of air flowing to chambers is same, so the amount of fuel is aproximately same. Or could be?
