Fueling control should be comparable (if not, that'd be good to know), so the only variables I see room for greater control would be ignition advance or knock retard (ECUtek alleged greater control on the former), and VVEL -- not slamming ECutek at all here. Just wondering what it does differently to net such a large difference?
