6.7 Powerstroke DPF Delete Problems – (detailed)

It’s time to know the cons of deleting DPF of 6.7 Powerstroke in detail. Let’s go.

#1. Decreased Resale Value

If you delete the 6.7 Powerstroke DPF the main problem you have to face is reducing the resale value. The main reason is the compromised emissions. In some cases, you won’t be able to sell your truck. That is because no one would like to purchase a car that they can’t drive on the road.

Moreover, it is obvious that once you remove any parts from your vehicle, its price will drop. And, when you are deleting a part like DPF, reduction of resale value is a must.

#2. Install Must Be DIY’s

The DPF system comes in pre-installed condition with the 6.7 Powerstroke. So, once you remove it, you can’t reinstall it through the company. That is because you make it uninstalled. So, if you want to install DPF again on your truck, you have to (DIY) do it yourself or contact an auto technician.

#3. Lose All Factory Warranty

You should know that, after you modify your Ford, you will no longer be covered by the limited or powertrain warranties offered by Ford. The issue arises when one considers the yearly increase in the price of maintenance. So, once you remove the DPF from the system, you bring changes to the vehicle. All factory warranties will be terminated now.

Remember, when an expensive breakdown or repair is imminent, the warranty is always a welcome relief to the owner. Trucks of any age might experience problems, so having insurance is always a good idea.

#4. Dealership May Refuse To Work

Once you lose all factory warranty, the dealer will refuse to work. Many customers have had this problem, as dealerships have refused service since the vehicle had been modified.

This is an issue if you have trouble putting your faith in standard mechanics. Ford dealership stops providing any service if customers modify or change the truck’s engine.

#5. It Is Illegal

Even if customizing your car is something you’re excited about, it might backfire if the police are on your tail. That’s why it is illegal.

When the procedure to remove the DPF is deemed unlawful, what happens? You won’t get far asking a registered tuning facility to remove the DPF. Finding somebody able to do so is going to be challenging because doing so could put their business at risk.

For your concern, under the Protection of the Environment Operations Act, 1997, removing, disabling, or otherwise interfering with an anti-pollution device installed on a motor vehicle is illegal. Companies can be fined up to $1500 and individuals up to $750 on the spot.

#6. Truck Will Not Pass Emission

As I mentioned earlier, if you delete the DPF, your truck will be illegal to run. The main reason is this emission. The EPA will keep tabs on you until you pass an emission test. This is a major contributing factor to the general difficulty of DPF deletes.

Well, emission test is a major issue in the United States and worldwide. In light of this, several jurisdictions’ emission laws would prefer to discuss your potential DPF delete with you.

#7. Harmful To The Environment

If you care about the planet, this is a major factor. The purpose of emission laws is to prevent environmental damage. If you take off your DPF, the exhaust gases won’t be cleaned. The exhaust from your vehicle will become a source of dangerous pollution if you do this.

The end result is that anyone too close to your car will have trouble breathing from the smoke. You will be worsening the air quality and rising to such a greenhouse effect.

#8. Adverse Issues With Engine Performance

Till now, I have discussed all the DPF delete problems except the vehicle permanence issues. Although a Ford owner can delete the DPF to add additional power, there are some risks of adverse issues with the engine.

One of the main DPF deleting problems of 6.7 Powerstroke is the high pressure on the fuel pump. Which may cause not starting or fuel leakage issues. However, this issue is rare. In this regard, you may read the article on “6.7 Powerstroke high pressure fuel pump failure symptoms.”

Importance Of DPF In 6.7 Powerstroke

Now, you know all the possible problems of DPF deletion in 6.7 Powerstroke. But this DPF system has some significance also. The diesel particulate filter (DPF) is a filter that collects diesel particulates, which are then burned off during the regeneration cycle.

The DPF is the third and final emission component that is included in the exhaust system of the 6.7 Powerstroke. Moreover, to avoid the problems mentioned above, DPF is very important.  

Are DPF Delete Problems Serious For Your 6.7 Powerstroke?

As long as I am in this auto mechanical field, I didn’t get any such cases of serious issues with the 6.7 Powerstroke engine after deleting the DPF. Moreover, truck owners seek this deletion to improve the performance of their vehicles. To increase the reliability and reduce the overall maintenance cost, such a DPF delete is good.

But after deleting the DPF, if your country’s laws don’t permit you to run a vehicle without a DPF, it will become a serious issue for you.

Can You Drive With These Problems Happening?

Obviously, you can’t drive with these problems happening. The main issue is with the emissions. As I told you before, without DPF, your 6.7 Powerstroke can’t pass the emissions. And without emissions, your vehicle is illegal.

But you can drive there in local areas where police and authorities won’t reach generally. But I recommend not to do so if such doing is illegal at your place.

The Original Equipment Manufacturer (OEM) system can be sold independently.

Everything will go fine if your country’s laws allow you. Otherwise, you can be sent to jail or fined. Not only you, but the technician who will help you to do it also can be fined.

Is it Good To Delete the DPF Of 6.7 Powerstroke?

Deleting the DPF is good only for the 6.7 Powerstroke vehicle, not for the owner or driver. It can improve your truck’s overall running condition but causes problems with resale, emissions, environmental destruction, and so on.

I recommend deleting the DPF of 6.7 Powerstroke only if it is permitted by law. Such a deletion reduces the cost of DEF fluid. Moreover, it increases horsepower by up to 100 with great tuning.

But, if the law won’t allow deleting this, then it will be best not to delete the DPF. Besides, it will be great for both you and also the environment.
