??? No, there is no reason the 2.4's performance should be any more dependent on air intake temps than the 2.0 on a percentage gained/lost basis.

I am not saying that the extra hp is not there under special conditions. All I am saying is that it is not what they measured when they came with the official engine catalog numbers.

"Special conditions" won't affect the new engine any differently than the old one. For sure they underrated the new car a little bit relative to old one. 101mph in the 1/4-mile for the new car vs. 95mph for the old one tells the story. New car makes ~20% more power vs. old. Which makes perfect sense as it has 20% more displacement and still makes peak power at the same 7000rpm as before. My stock '17 dynoed 179rwhp. New ones dyno ~210-215? Makes sense.
