On my 07 4.7, I can honestly say that I can't tell a difference between performance, 87, mileage, or stock (never tried towing) with my superchips. There probably is a gain in performance, but I really can't feel it. There might also be a small gain in mpg, but it's half a gallon or less on my truck (still under 13 mpg on hwy).

I'd like to say it makes a very noticeable difference, but it doesn't from my experience. So my opinion is that it's really not worth it for the older 4.7s. YMMV.
