Emissions information.
I was at work today and talking with a guy who has a friend who runs a diesel mechanic shop. Log sorry short he said that you can remove the dpf system like it clamps off and can be replaced with a pipe and the egr can be removed - basically all emissions stuff can be removed. He said doing this will help prolong the life of the truck.
I told him.,,, wouldn't that void the warranty? He said the only time it would void it is if the truck had something mess up on it and I didn't put the emissions stuff back on when I take it to the dealership.
Is is this true and can this work?
also if it does work.... how long is a safe time to begin removing emissions stuff?
thanks

Removing the emissions controls on a modern diesel is not uncommon. It involves removing the DPF and disconnecting the DEF injector and potentially bypassing the EGR system. It requires using a tuner program to tell the engine computer not to attempt to regenerate or inject DEF. This whole process is called "deleting."
Overall, deleting will improve fuel economy and possibly increase power. The only thing "harmful" about modern emissions controls is the active regeneration process and large amounts of EGR. It might be helpful to prolong life, but I doubt the difference would be drastic.
Its also a violation of Federal law, and states that require emissions inspections will obviously create a problem if you are deleted...you won't pass.
Warranty for the entire engine can be denied if you are deleted. Some dealers are pretty lenient but others are hard nosed and certainly if a regional rep gets involved, deleting can certainly be a reason for warranty voiding.

As said above, and even if you reinstall stuff they can still see the computer was tampered with so again depending on dealer. However, it doesnt void warranty on everything. Just engine related stuff and those usually tend to be good for a long time. The ones that have issues usually have issues early on.

Oh so if I put the stuff back on they can still read it in the computer... hmm. Well also I live in a no emissions state- with that being said would that play in my favor at the dealer and how reliable are these engines?
Like is the 6.7 known for having any issues? If so that would make me want to wait on the delete

The 6.7 has had a couple of hiccups. But more importantly, if you delete, you become your own powertrain warranty station, in addition to the aforementioned federal issues. All of which have financial implications.

So pretty much the best thing to do in this situation is just ride out the warranty and then delete after. In all your opinions.

At least. And even then you must assess your risk tolerance.

Ford certifies this engine to 250,000 miles before any major engine rebuild.
The only scenario I can ever imagine deleting is if the DPF needs to be completely replaced and the cost is exorbitant. In the meantime, by not deleting, you're helping keep the environment cleaner.

Every diesel tech that I know will tell you that the emissions equipment is troublesome. Most that have diesels have them deleted. If you go this route you need to be able to put it back to stock as it's illegal for a dealer to sell a deleted truck if you decide to trade it in later

In my state where HD pickups are exempt from emissions inspection (safety only)...there are simply tons of deleted pickups running around. Plenty of 6.7L Fords.

To the OP, Im not saying dont do it. Ive done it before. However, as stated the gains arent what they used to be on older diesels. And yes its illegal no matter the state but many dont check and youd never be caught. Another downside is if you tow, even with clean tunes, youll have aome soot on your trailer. A pain if its a camper or something. First thing id do is talk to your service dept to see how they feel and then go from there.
