did you notice a decent difference in power it says its only about 20 hp extra :(

Mine was not preloaded with any tunes. All custom so cannot honestly compare.

Superchips and EDGE seem to be the favorites for the 2v 5.4L based on what I've read here, and all the F150 people I know running them.

Not sure of your mileage but with your tuner make sure to freshen up your plugs, plug gap and coil packs(if needed).

#4 and #8 are behind the firewall. Just like any plug, just take your time. It will take you an afternoon to do all 8 plugs.

Extensions and swivels is all it took for me. I have a really good mix of 1/4" and 3/8" ratchet tools and I was able to do the job in about 2 hours.
