You'd think that, but the reality is somewhat different:

A properly designed intake manifold would be able to surpass even the gains of individual throttle bodies, simply due to the overlapping of the sound waves causing air to resonate and form a charged air pulse...

Simply put; itb's can be outperformed by a single throttle body and properly matched and designed intake manifold.

The downside? You better know wtf you're doing when designing your setup.

Itb's look and sound badass. They also have this insane throttle response..... But they are finicky in that tuning will take you a bit longer to make them daily driver streetable - you'll have to get acquainted with tuning via throttle position vs. map sensor. All in all, they're not so bad.
