That is absolutely correct. The torque dip has absolutely nothing to do with fueling. It's all about VE of the engine across the rpm band. The torque dip is due to a combination of intake manifold and head design. Otherwise, they would have tuned it out from the factory and we wouldn't be having this discussion.
