I have a 2015 that has never been firmware updated, at least to my knowledge, so not a firmware issue. I think you're just being too gentle with the pedal relative to the factory values, so when it adapts to how it thinks you want to drive you perceive it as being sluggish. See if it goes away if you just stab the pedal a bit more than you're used to.
