I have not used them on a Ford but I have used them on Chevy's and I have been pleased with it and am using one now on a 2000 K3500. I am not sure what features are supported on a Ford though because I like the ability to tweak speedometer too but I am not sure if that is supported on a Ford. |

While my response isn't directed towards the 5.4 Liter engine directly, it is geared more towards chip tuning in general, and again, this is my opinion.
Overall - I've never been overly happy changing the chips or modifying the computer settings in any type of naturally aspirated engine. The net gains (torque, horsepower, fuel mileage, etc.), in my opinion, are minimal at best and may take years to get any type of return on your investment. Also, in most cases on motors built since 1987 (or so), it takes weeks for the computer to re-learn how to adapt to the changes made and during this time you can even see a drop in performance / economy.
On a vehicle that is turbo charged however, the gains are quite substantial and you can see immediate results. There is still some time needed for the computer systems to remap to the changes made, but in my opinion they aren't as drastic, as compared to the initial changes made.
Some of my opinions are based upon some older tests we did with naturally aspirated vehicles and with some other turbo-charged diesel engines. While we've seen great results on both sides, if you compare them against each other, the gains on a turbo-charged engine are supremely larger.

I cannot speak for a Ford but with my GM truck it greatly improved part throttle responce (and my truck is not drive by wire) and power and boosted MPG some too and the engine just "feels/sounds" stronger too. |
