Sorry I didn't add this to my initial question, but I've got the 4.7L V8, which does not have a MAF. I has only an air temperature sensor in the air tract. Technically, with a cold air intake, the temp sensor should read colder air will cause the pcm to map the cooler air as denser and thus add fuel to maintain optimal air/fuel mixture. More air/fuel to burn equates to more power, as long as it burns efficiently. The same should be true of a MAF which measures air density - more, cooler air would cause the pcm to add more fuel to the mixture.
Anyway, I found my exhaust leak this last weekend coming from the ball joint flange between the cats and the muffler. Just need to get that fixed.
