So if I am understanding what you are saying Denny, then perhaps these add on intakes are only helping because they are tricking the ECU into running leaning A/F mixture? So...perhaps a good dyno tune to adjust the A/F would be just as beneficial, maybe even moreso, than a CAI? Do you think a CAI + tune to adjust A/F would be even more beneficial?

I don't have any experience with working on these newer cars, but when I was building small block chevys I certainly didn't use the biggest 4 barrel I could get, in fact putting too big of a carb on would actually hurt horsepower.
