I'd like to add one other observation to this post. I noticed the hesitation on my '02 Box S from day one, especially on heel/toe down shift blips. After installing an Evo Hi-Flo air filter, secondary cat bypass pipes and a sport muffler, that hesitation is virtually non-existent. I think letting the engine breath a little better has cured most of that hesitation, as opposed to an e-gas problem.

Perhaps an expert could chime in on my findings?
