adding chip to F250

[3ares]

I have a 2016 F250 with a 6.7 diesel, 6 speed automatic. Has anyone tried putting a chip in one of these trucks to get better MPG and do you think it would harm the truck?

Thanks,
Happy Camping

We can all agree, don't buy the tornado. Haha.

I can speak for GM but likely the same for all the big three. When it comes to major powertrain warranty claims its not a dealer call (regardless of how tight you are with them). GM corporate will request an ECM snapshot. So if your CP4 takes a dump and takes out the entire fuel system just make sure you have $10-12k on hand to cover the cost because corporate will deny your warranty. Now if you power window does out that's a different story and why I said a programmer will void your POWERTRAIN warranty, not bumper-to-bumper warranty.

That is on reason why I didn't go with a GM or Ford back in 2014. I knew that I was going to tune and modify my truck long before the warranty period was up and was more afraid of voiding the warranty on the Ford and GM due to the CP4 than I was with the Cummins and the CP3. Not saying it would have happened. I was just a little more afraid of it in those trucks due to it happening to people I personally know and what I read in the forums.

Thanks to All for your replies. From what y'all said, I'm leaving my truck the way it is.

Thank you

You're a wise man. IMHO, modern vehicles generally have more than enough punch...stock....and get decent MPG.

Plus it gets old when people incorrectly say "it will void your warranty." It can void parts of your warranty, but only related to what you changed. If you delete and tune your truck and a window motor goes out, they will have to fix it. If it's related to things you changed, then you can be out of luck. But that too depends on your dealer. I've had dealers take care of it anyways after doing many aftermarket modifications.

Tell me about it. I get that silly comment every time someone finds out my truck is tuned and yet my dealer still does warranty work on many other parts of my truck. I just look at them like "Sum B---h! I am a grown man. Do you pay my truck payment? Do I ask you why you leave your truck stock? Then mind ya business!"

Not to mention a large percentage of warranty work is because of emmisions stuff failing or causing excessive wear/heat on other engine components.
Factory programming is based heavily on making your truck quiet and clean. If you care less about those than the factory, you can improve fuel mileage. It isn't a huge a gain as some people claim, but it is real.

Straight out I wasn't even asking you, btw in Ma it is illegal to alter your emissions and it has to be fully functioning for the yearly inspection.

Chips was a TV show from the 80's...

Diesels use "programmers" and yes all newer diesels for the last 10+ years leave a footprint when flashed that the dealer can see and will void your powertrain warranty. No way around it. The Duramileage thing is pure snake oil...

[ShinerBock]

Then don't ask why!

Nor should I be lectured by you when I only asked the question of "WHY"

[ShinerBock]

Most people, myself included, understand full well that all or parts of the warranty will be voided when tuning a vehicle. We still do it because to us the benefits out weigh the risks just like others choose not to because the risks out weight the benefits. Different strokes for different folks!

As long as he is paying his truck payment then I don't see it is anyone's business as to why he would want to do it as long as what he is doing is not illegal or negatively effecting anyone else. Nor should he be lectured on warranty if he has already accepted the fact that he will loose it. It is up to him if the benefits out weight the costs, not anyone else.

Why??

...say goodbye to that warranty!

If that is not a chip or programmer, what is it? According to the video, the guy says it is "warranty safe" because the vehicles computer will not "know" that the thingamagig is installed - I find that hard to believe. Of course, no where is it said that it is "warranty allowed". Interesting and very careful use of words.

That thing might work, but along with most others here I wouldn't put it on an engine that is still under factory warranty.

From what I understand it is a computer that ramps the fuel up from the vehicles computer signals. I'm not trying to sell the thing and I don't have one either. I have been thinking about getting one though and trying it out. Not for the claimed fuel mileage increase but for another reason. The reason it is called warranty safe is because it can be unplugged and removed before taking the vehicle in. It is installed after the computer so it don't change any of the computers settings so they say it's untraceable. IDK. It's not "warranty allowed" because anything you put on your truck that is aftermarket has the chance to void some warranty. A simple grill guard could void a warranty.

Roger that! I actually did think you had bought one. Thanks for the clarification.
