I've debated swapping to a carb or spending more & switching to a Holley EFI set-up that's NOT TBI based. Most likely it will get a carb because big-blocks in CC duallys aren't exactly efficient so it seems ROI would be nonexistent.

where did you put to o2? how do you like that intake? did it make a diff?
