Depends on the car, its sensors, driving technique, and the design of the intake--seems to me. My WAI works. I have long wondered about a CAI. I think one reason for the WAI in colder climes is for warm up and for dealing with denser colder air of winter. I would think a CAI would work for accelerating with load as long as you were also using EOC to reap the benefit of the shorter pulse through a longer glide.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
