Re: tuner help
They work by backing up the stock tune files and loading in new tune files, the backed up file is "mated" to the tuner so if you ever wish to sell the tuner you have to "unlock" it by reloading the stock tune.
You can read your own trouble codes and do diagnostics in the form of data logging to check parameters and such if you wish. I think you can clear codes as well.
You can read other compatible vehicles trouble codes as well.
The bad is a mail order tune wont give you any gain really unless its from someone that knows the car and writes a custom tune for it. You can find a tuner in your area or somewhere that has a good reputation that can get you better numbers than just ordering the "can" tune as they call it.
I would expect 5rwhp-10rwhp from a can off the shelf crappy tune and 10-20rwhp from a better custom tune, its not all rwhp/tq that you gain you can modify shift points and such (great for autos)
You can modify your rear ratio/tires if you ever change that with the tune
If you ever lose the hand held or it dies you can get ford to reflash if you wanted
you void your warranty if you load a tune on your car, if you had one still
tunes are always best when done with mods, if you change/add mods you may need a retune to make best use of it, some mods REQUIRE a retune.
