Magnuson-Moss act only partialy applies, as your vehicle does not come with a "full" warranty but a New Vehicle LIMITED Warranty. I do not want to hijack this thread so read and UNDERSTAND your warranty info before taking the plunge. Don't rely on Internet hearsay and misinformation. In the end it is YOU who will pay. Been there and done that many times on the manufacturers side of the courtroom / mediator

When there was a significant benefit to it, chipping and tuning gas engines was popular. As the factory performance improved over the years the benefits of aftermarket tuners decreased to where you don't seem much of a market for it anymore. Diesels used to be real sleepers with a lot to be gained from aftermarket tunes, even more so than gas engines. Seems the factory is doing much better now so the potential improvements probably don't outweigh the downside for most. I think we're about to the point where tuners are a thing of the past. If not for market reason, OBDIII will probably make them impossible to use without being reported.

Probably more tuners being sold today than before diesel emissions DEF/DPF came onto the scene. Tuning is not all about increasing HP/TQ figures for many. Like it or not the most UNreliable aspect of these nee trucks are the emissions systems.

1) Chips = gas, tune/tuner= diesel

2). Your going to get a lot of "opinions" here from those who have never used a tune, know much about them, or those who use them. IMO go to a diesel truck specific forum to get the real deal on diesel tunes.

I did a lot of mods on my 03 Cummins and it helped in all aspects.
After towing my TH this week with my 16, I have no desire to add anything.
These new trucks are amazing. I slowed to 50 due to traffic up a 12% grade and was able to accelerate back to 60 easily. Faster if I had wanted.
My advice is leave it stock. Not worth the risk. The computers record "everything".

Your warranty is not voided using a tuner unless the fault/failure can be traced back to a change created by the tuner. If you are willing to go down this path, you need a good understanding of what you are changing so you can either fix things yourself or be able to have an intelligent conversation with the person that will be working on your modified vehicle.

Not true: the Ford warranty and policy manual says: Any modification to the vehicle after it leaves the plant will void the warranty.
I'm sure if you did a headlight upgrade it wouldn't void it but theoretically it can. I saw several warranties voided completely from chips and tunes, nitrous and other things. A few of those went to court and the manufacturer won every time.
Good luck with your decision.

New diesels are absolute BEASTS..bone stock.
Leave it alone and get on down the road.
The only thing you will accomplish is ...trouble and grief.

The diesel repair shop I use, also does performance work. I couldn't believe how many newer diesels he's taking in and doing the deletes and tuning them. I guess these guys have enough money to not worry about warranties and repairs.
