there is no need to replace the air box to stock. They dont care that there is a CAI on the truck, that voids nothing. They(Ford) just ask the dealer to check if the truck has been modified in the event of some MAJOR failure. Again I have never ever seen this happen at any dealer in our area or heard of a dealer denying claims. Keep in mind we had alot of training on this subject matter. We were also made aware of the moss magnassun (sp?) act. It is on the dealer to prove an aftermarket part caused the failure.

Either way this whole warranty thing has been blown way out of context by forums like this where everyone shoot off aimless "facts" in which they have no credible proof or dealer experience.


Return to stock, and you are golden.


PS But be careful because some people on this site may think you are a thief and destined for hell because you cheated Ford out of warranty work by fooling them with the tuner-return to stock trick hahahahahahaha

I agree , mods help performance, but come on, really???? a simple air intake mod, tuner, exhaust is not near enough of a "mod" to put undue stress on a truck . Ya, they help, but it is not a mod like swapping out heads, cams, headers, injectors,ect. you know, real MODS . I too have the intake, tuner, exhaust mod. Helped the truck alot , but not like truly modding the engine does. Always return your to stock tune before taking to the dealer , and all is good.

What happens if your truck breaks down and you can't get the tune switched? Or is it always switchable to stock regardless of the breakdown.

Depends on if you can turn the key to the on position and have power.

It's completely fair for Ford to deny warranty service on a tuned vehicle. My daughter's boyfriend has a Challenger 500 which he tuned using some code from a "specialist" in the US.

After installing the tune and going on a highway trip he holed a piston. It turns out that there were a few owners who bought this special tune who also holed pistons.

It would be extremely unethical to take this car back to the dealer hoping to make a warranty claim.

The manufacturer spends millions trying to design a system which provides good performance with longevity. A tune is never aimed at longevity as its primary goal.

There always has to be one. Unethical? Really? Tunes are not meant for longevity? Really, and you are who? Tunes that most of us get here have absolutely no impact on reliability. The are designed to help improve economy and every day driving. You run into a rookie tuner who doesnt know what parameters to adjust and you can blow a motor or you tune it to race and there ya go.

The REASON it is strongly urged to return the truck to stock from a tune is because the SMALL chance the dealer would flash the PCM/ECM. NOT BECAUSE WE WILL EVER SEE YOUR TUNE ON IDS. The IDS is used to diagnose and run tests, change things etc. There is not a little screen or button that shows us changes to the stock parameters.

Its to be safe that you should return it to stock, not because the dealer will see you have a tune. So if your truck breaks down and will not crank/start dont sweat it. We will not re program your pcm, its something else wrong with the vehilce

If I had a U-joint, or a driveshaft, or a water pump fail under warranty, it's unlikely that the dealer will examine the PCM to see if it has been tuned.

That being said, I'd return it to stock for the visit - why take a chance.

only takes 15 minutes to return to stock and a few miles, be safe and do so. Shop manager having a bad day could turn yours the same

All those who spent hundreds on a tune to increase the life of their motor.... Raise your hands.

Yeah, that's what I thought. Nobody.

And just for the record, I have nothing against guys using a tune. It's your truck... do what you want.

Why do you think the tuner does not affect the injectors? How do you think it alters the fueling / mapping? It varies the cycle, duration, and frequency (in some cases), of the fuel injector operation. In this case, cause and effect is clear.

Or maybe I am misunderstanding what you mean by "edge tuned".
