Anything that increases flow can lead to a lazy bottom end. More flow is good at high rpm, but at low rpm the velocity of the inlet air charge often suffers, and therefore response. This means a bog or slow response. Then you get a lightswitch beast. A dog at low rpm, a screamer at high rpm.
This is an excessive example but it points out the dance that good designers balance in their products. Don't think maxing flow is the way to go.
