I noticed distinct improvements in my '02 4.7. The 91 octane performance program was a decent scorcher. But I run the 87 octane performance program for my everyday driving. It gives a good mid-range boost in power, and way firmer shifts. But don't expect to just toss it in and have a pavement ripper. It's just another piece of the puzzle as far as the quest for more power goes.
