Then again, I'm not an engineer, I'm just going off what I've read and heard.

Several others have also pointed out that the Cayman (I think it was a Cayman) also has a similar dip, albeit less-pronounced (or perhaps less an issue due to higher power/torque), suggesting it might be an engine characteristic.
Others have mentioned/explained that the dip is what allows the FA20 to provide reasonable low-end torque (i.e. below 4k rpm) for city driving, while still managing 200hp from a 2.0L NA.
Torque dip pairs well with spinning doritos.
