Superchips are good, and i know Bully Dog makes a good gas tuner... tuners are extremely effective on diesels, not so much on the gasoline engines but they do make a noticable difference. On a gas, the tuner will give you anywhere from 15-30 HP, and i'm guessing the Superchip has different performance levels. I have a Hypertech on my old body style Expedition, and it makes a small but noticeable difference on the performance. It will also give you up to a few extra MPG. Sounds to me like you're ballin', so go ahead and get one. Good luck buddyI have an '07 ford expedition eddie bauer el with every option on it and i want to know add a superchip?
Fords do not have removable chips. An external programmer is needed to change any of the parameters in the PCM - and any performance increase will depend on the changes that are instituted.
