Most folks believe it it's an error..it is not.

how does a lack of low - mid range torque increase driveability???
It's always been my understanding that the torque dip was a byproduct of the dual fuel injector setup. It's optimized for low rpm torque and fuel economy via the Port injection, then switches over to direct injection to get the power in the high RPM's where it can more accurately introduce fuel.
The torque dip isn't intentional, but it's accepted as a byproduct of the engines "dual power band" characteristic. As shown in above graphs, you can tune it out to an extent, but at what cost? Fuel savings?
