Not quite true. In the case of the V10, the stock intake is such a restriction that opening it up using an AFE intake allows more air under all throttle positions. The MAF sees this and adds more fuel, which means it makes more power for a given throttle angle. This allows it to pull harder in overdrive without so much downshifting.
Disclaimer: I had the Banks PowerPack on already when I did the AFE upgrade. I don't know how much improvement it would make with a stock exhaust.
