Tuners and factory warranty ???
The bottom line of the Magnusson-Moss Act is that if it's YOUR vehicle, which you have purchased, then you are free to make any modifications you see fit to said vehicle. In the event of a problem that's still covered under the original warranty then it is the DEALERS obligation to prove that any such modification you've made actually caused the problem if they decline to repair the problem under warranty.
I think that's why some dealerships don't question things like cai's or even tuners as long as it's not something outlandish. These trucks should run just fine with "normal" mods. Would cost 'em more to fight fixing stuff that shouldn't go bad anyhow.
Now, take that truck in with the whole top end changed (supercharged, NO2, etc.,) and yeah, they'll never pay for fixin' anything. I think no judge or jury would have much sympathy for mods like that, not that there's anything wrong with that; just don't expect the warranty to cover cooked valves, cracked heads.. whatever.. if you go that way.
In my case, I still return it to stock programming and even put the stock intake back on when I've gone to my dealer. I've never had any problem with the truck, I only take it in because my dealer does the oil and tire rotation cheaper than I could do it myself.
Hey, they have Shelby Mustangs in the showroom with basically the same mods I've done with my truck. So I think they'd have a hard time proving that a cai and reputable tunes do any harm to their Ford powertrains.
Once my warranty is gone tho, I'm looking for headers, e-fans, etc. LOL

There was a post on here a while ago about an 08 F250 PSD that got a new engine. This was a members truck on this forum and it had a tuner on it and he traded it in for another PSD and another member just so happened to buy it and the engine went. The member that bought the truck also put a tuner in the truck and got a new engine for his SD that had about 12k on the ticker when it went. Here is a link to the thread https://www.f150online.com/forums/sh...d.php?t=327288. It all depends on the dealer with mods to your truck. I would definatly call the dealer you are purchasing the truck from and ask what there policies are about mods.

I was just about to order a Gryphon, From( Power hungry Performance)and on there products page, in the manual it say that even if the tuner (any tuner) has been removed the dealer can still detect that it was on. So I give Them a thumbs up for at least saying it.

That's the case for many vehicles but not our 2004+ F150s. It trips a code saying that it needs to complete a drive cycle. The same thing happens when you disconnect the battery.
Much thanks guys....
Great post TexEdition.
I think that I have decided to basically run the truck without a tuner for a good solid break in and testing. Then later, add the tuner. This way, if the truck has any problems, I won't have to wonder "IF" it has anything to do with the tuner setup. Besides, it would probably be nice to see how the truck runs and feels "stock", so I will be able to see any differences the tuner makes after I add it.....
Thanks again to all who have replied,

FoMoCo has no way of detecting your programmer when returned to stock. A rumor sprung up when the new Powerstroke's came out that they could detect it.
FoMoCo can not make you replace parts with FoMoCo parts. You have the choice to use any manufacturer you want. Just tell them your wife ran over your intake when you had it off for engine detailing. Along with that damn boulder that destroyed all of you exhaust from the cat's back.

There has been alot of discussion over this in the past, I too would like a definitive answer as to whether the dealer can tell if you've had a tuner on, not just an "I don't think so" from some of the so-called experts. I would like to hear from TROYER , JUSTIN at VMP,or BILL at Power Hungry Performance ( Gryphon) They must have a sure answer as to whether the dealer can detect a tuner.

The answer, technically, is yes. There is a service mode -- code 6, I believe he said -- that will alert the tech to the fact that the computer has been reprogrammed. He also told us that most techs don't know to look for it, but it IS there. If for some reason, the computer has to be sent to Ford, they WILL know that your computer has been reprogrammed.
Hope this helps.

I am not Bill, but I know the answer after asking this question of one of our customers who works at a Ford dealership (thank you, Shane!).

In other words, if the PCM HAS been reflashed (probably likely on older PCMs to get rid of deficiencies in the oriiginal firmware), will our aftermarket programmer "reflashes" look any different?
Hope I've made sense with this question. I'd like Shane's and Bill's thoughts on it please. And Corey, I think I speak for all of us when I say I/we appreciate all the work you do to keep us informed. Thank you!

As someone who understands a bit about programming microprocessors, I tend to "favor" the idea that the microprocessor "knows" when it has been altered and can tell anyone who asks (in the right way) that it has happened. This is NOT a difficult design feature - in fact it is trivial, so I expect the PCM designer would have included it. I would have.
The real question here though, is when we return the PCM to the "stock setting", does it reset all of the codes (bits) to the last "approved by Ford" setting?
It also seems to me that if a GOOD programmer makes a copy of the original "stock" setting in the PCM when it upgrades it to our new and improved "burn rubber" level, it should be able to return all of those "bits" back to their original levels - including the "I was changed" ones.
This is what I'd like to see answered. Someone like Bill who has an intimate knowledge of the Gryphon/Edge programmer design, not just the engine or PCM of our beasts, could answer it. (Did Justin or Mike have anything to do with the hardware design of the Xcal? If so, they could answer it too.)

I'm not completly sure about it but from a lot of people's understanding that is how it works. I'd like to know what Justin and Mike think about it.
I like the new girl better, she's a lot more innocent and younger.

Thank you for taking the time to post that, Toolcrib. That means a lot to us!
It may hurt our business, but we'd be lying if we told customers that there is no connection between having a programmer and the vehicle's warranty. What sucks big time is that many dealers will use it as an excuse to void the warranty even when it's not the fault of the programmer or any computer reprogramming.
Totally unfair!
