To tune or not to tune…

[SubZombie]

Call your dealer and have them put in writing that the tune will not deny coverage of your 7yr/125k (or whatever warranty) if a valve drops out - They can not write that and will not. I called over a dozen dealers with the same question of “Will this Ford Performance tune effect my extended warranty,” and nobody could write “No, the tune will not effect your extended warranty” due to the tune being able to cause damage. However every single dealership expressed if you get all your service work done here, pay for the recommended services / extras, etc., they likely will NOT deny your claim because you have trusted them with your vehicle.

The Ford Performance tune comes with a Ford Performance Warranty, good for 3yrs/36k miles since the original date of the vehicle purchase. This warranty covers all items affected by the tune.

If a failure occurs AFTER 36,000 miles and Ford determines it was caused by the tune, it will NOT be covered under the factory powertrain warranty. This includes up to your 5yr/60K. And it is very easy to blame the tune (even though its Ford Performance).

This is the caveat - you should have a very good relationship with your dealer to have your truck covered. You can’t expect to get a tune, drive the piss out of it, a valve drops at 60k miles and you say its under warranty…they’ll say the tune and lack of maintenance caused the valve to drop and could have been caught by reoccurring dealer maintenance.

Idk what you do for a living but if you had any actual clue you would realize how ridiculous it is to ask any dealer or business put anything like that in writing. It’s not something that happens. Nuts like you try and get me to reinterpret shit in words they like all the time in writing. It’s just not how it works, I don’t care if it’s for something of no value and it’s already spelled out. It’s usually some grandpa who expects a corporation to function like a mom and pop shop.

There are literal court rulings that directly conflict with shit you’re saying. You don’t know what you’re talking about. Have fun living under your tin hat.

I do work in a similar industry and I can tell you there’s a reason we do not put in writing that any modification will be covered.

Buddy, whatever works for you and makes you feel better at night, do it. I’m explaining for me, after xx phone calls to dealers and talking with my ASE friends who work at dealers, blaming fault on the tune is a great way to get transmission / engine coverage denied out of warranty IF you are not a repeat customer or bought your truck there. Not that it will happen, but if it happens. and it’s a gamble I won’t take.

I'm not going to explain in detail how the warranty works because it's been done so many times but your understanding of it is incorrect. The 5 year 60k powertrain warranty is absolutely still active even with the tune. I have it. I've used it. I spoke directly with Ford and dealers about it and confirmed it. The 3/36 is additional coverage, not in place of. It literally says that in the material it comes with. I know a lot of people like to think everyone is conspiring against them but

well theres a reason im asking tbh. Ford performance website isnt very clear about it just says 3/36k. It dosnt say if that adds to the warranty (idk why it would) or if you just get 3/36 from the date of install and that overrides your warranty currently. Which is more of what id expect. Unfortunately taking dealers word for it dosnt mean much.

dealers especially here insocal will get iut of any warranty work unless its blantantly obvious (diff exploded etc). I did have a tune on my mustang and they never checked when powertrain parts went bad. But that car had a history long before that

He hasn’t read it in clarity and understands it like you do.

You get 3 years / 36k from the date the vehicle was sold. If you loaded the tune 1 years into ownership, you have 2 years left.

Your 5 year / 60k is intact and valid. But IF the problem is caused by the tune, you’re out of luck.

All extended warranties are still good, unless the problem is caused by the tune, then you’re out of luck.

PS any engine / cooling / transmission / differential issue can be pointed back at the tune. Heck even upsizing tire size and then losing the trans can void your warranty. The other guy with the 5 years old grammar is referencing the Magnuson Moss Act - but doesn’t understand all these systems are related with a tune.

100% correct. I went through the same process with the dealership and they pretty much said exactly the same thing. My extended warranty is worth more to me than a few extra HP.
This coming from a HP junkie by the way.

FYI - Go to Ken Grody of Buena Park. They will be the only store around here that if you get all your work done their will likely honor your extended warranty.

Are you a mind reader? Do you know anything about me? Do you have the tune yourself? Have you had any warranty work done with the tune?

no?

Then maybe someone who can say yes to all that is more qualified to answer? Especially since youre talking out of your ass with no first hand experience getting work done with this specific tune or any ownership of it. You’re just trying to reinforce your opinion based literally on speculation.

And thats fine, but don’t act like you are stating facts when you haven’t done any of it.

I will also say that if you had responded with this, instead of your initial reply (which, as anyone can see, specifically says ‘you only have a 3/36 now’ or whatever) I probably wouldn’t have even replied. Your initial reply was blatantly false. Now you’re back tracking.

Really want to (aftermarket) tune my RR, but haven’t yet done so due to potential ramifications (My truck is only 2 months old with 1500 miles on it). I found this article from Ford Authority interesting and plan to either use the Ford Performance tune or do nothing for now… like many other decisions in life, it ultimately is a gamble that some win and some lose. https://fordauthority.com/2025/10/f...hlid=ee4fc4e942e503a50de91fea5c30d7a7edd45185

I installed the Ford Tune on mine at 1,500 miles or so. It went fairly smoothly. Make sure the Firewalls the Computer you use are turned off before starting. After that it is simple and works well. I can definitely tell the performance has picked up along with the fuel mileage. So don’t wait, buy it from Tire Rack. And get it done.

Okay now you've removed all doubt.

A warranty is really simple. You can add whatever you want to your truck. Adding something does not automatically void it. Now if you add something like a tune and your truck messes up Ford had to prove that your tune was what caused it in order to not cover it.

Yup, dealer’s discretion now instead of it automatically being covered with no questions asked.

Well, i wouldnt go that far. Its still dealer descretion without the tune. If they say you didnt do your oil, or you drove it wrong, they can still deny. Its always dealer descretion once you buy the truck

You are correct!

it’s not at their discretion at all. They have to prove your modification caused the issue. Can they just deny it without actually looking into the issue? Absolutely. Can you sue them and win if they do that? Absolutely.

Maybe. Here’s an example…on my 2019 Tacoma, I changed the wheels and tires, along with UCA and shocks to Kings and Total Chaos.

I had a LCA problem. They denied to cover it while under warranty due to modified suspension. Was it worth me pursuing legal action after them? No. But if all my suspension was stock, it would have been covered.

All I’m saying is there is a definite grey area here…thats it. If you can’t agree with that then you likely have a tune and extended warranty, and are hoping you’re covered
