Mods and Warranties

You don't want to go in with the car’s computer program other than the stock program. If you use something like the Xcal2 for reprogramming, you can at least load the original/stock program before going in for service.

No dealer will give you a separate warranty agreement based on the mods you put on.

While it is true that a problem must be traced to the mod for Ford to deny the claim, it must also be stated that the burden to fight the decision to not cover a problem is going to fall on the consumer.

The mods you list are pretty benign and will not likely result in a dealer not honoring the warranty, except perhaps the retune. Real trouble comes in when you add anything that gets inserted into the drive train, like pulleys and of course superchargers.

I've seen numerous people that have gone into the dealer after usign an xcal2, some flashed back to stock, some didnt, and nobody that i have seen has had a problem yet.
If you did all these mods and your fuel pump failed, they will have to fix it, no questions asked. If your mass air goes out, thats a different story, you might have to fight that tooth and nail.

Basically you wont know until you go in with that situation, every dealer is going to be different.

They cant claim an intake cause you to throw a rod, it has to atleast be "reasonable"
