How To Pass Emissions With A Deleted Diesel?

The EPA allows for the removal of an emission system legally, but the vehicle must first be reconditioned and a new label as well as certification must be installed. Before your engine can be certified, it must undergo a thorough inspection. As a result, no one can validate it with a piece of paper alone.

Is it possible to pass emissions with DPF Delete?

Can Dpf Delete Help You Pass Emissions? Diesel cars with DPF deletes used to be able to get around emissions limits. However, it is now much more difficult. A diesel that has been disabled will now pass any emissions test, regardless of which country you own or how far you travel.

Is it possible to pass emissions with a diesel truck that has been deleted?

There is no way around it; tampering with or modifying your truck’s emission system in any manner is completely unlawful. It is not a state or local law (though such do exist), but rather a federal law. The first thing clients remark when we discuss this is that “it’s only for off-highway use” or “it’s only for tractor pulls.” They believe that by doing so, they will be able to avoid any laws, but this is far from the fact.

Yes, your emission system can be lawfully removed from your vehicle, but it will require recertification by the manufacturer and the issuance of a new emission label and certification. You can’t just sign a piece of paper and declare that your engine has been recertified. You’d have to pay to have your engine re-certified by the original equipment manufacturer, which is a costly process.

Myth #2There are no EPA Police

This is technically correct. A federal emission law, on the other hand, can be uploaded by any state or local government. This is the same as someone saying, “There are no IRS cops, but the IRS can collect and enforce laws from a building thousands of miles away.” The extent of testing and enforcement will differ depending on your state and county.

Myth #3 – The EPA doesn’t go after the little guys

Another prevalent misunderstanding among clients is that the Environmental Protection Agency (EPA) does not target small enterprises. For your convenience, the EPA maintains a list of every single resolution filed against the Clean Air Act for cars, organized by year. Cases range from tuning equipment providers being taxed over $4 million to a single owner doing a DPF delete on a single car.

If you think you’re “too small to be noticed or cared for,” rest assured that you’re not. It only takes one employee or service provider to report the problem, and you’ll be in serious trouble in no time. If the removal/tuning has been done frequently or on a wide scale, the cases might be both civil and criminal.

The fines can quickly mount, since the EPA has the authority to levy civil penalties of up to $7,500 per day for major violations and $37,500 per day for minor violations.

Myth #4 – Only California Cares about Emissions

We get calls from county and state governments asking for a software solution to detect pollution manipulation on commercial trucks on a regular basis. We don’t have a response yet, but I can assure you that someone is working on one right now. There is a sizable demand for a device like this. The reason for this is that the fines are so high that a government agency might pay tens of thousands of dollars each month for that software and still make a profit.

California isn’t the only state with this problem. Several counties in Texas already require emission testing on commercial trucks, and states like Minnesota, as well as New York, are following suit. They’ll find a means to collect fines if there’s money to be made!

Myth #5Deleting my emissions will solve all my problems

This isn’t even close to being accurate. Your first task will be to find a competent “tuner” to assist you, and based on our experience, there are more incompetent ones on the market than competent ones. To be honest, the truly outstanding tuners aren’t promoting because they know what they’re doing. In terms of technical expertise and capability, the ones that do advertise are often at the bottom of the totem pole. They frequently clone one ECM software to another without thoroughly inspecting the intricacies.

So, what exactly does this imply? It indicates that if your engine is tuned by a bad tuner, you will have serious issues. Poor engine performance to your engine flinging a rod through the block are all possibilities. Inexperienced tuners, for example, will often remove the EGR on the PACCAR MX engine. The EGR, on the other hand, cools the combustion chamber. With the EGR removed, your head will crack, and you’ll be dealing with a far worse problem. Modern engines are built to work in harmony with all of their components, and changing one component might lead to more serious issues. If you think it’s just MX engines, consider this Facebook user who had an ISX removed:

Aside from these urban legends, there are a few more things to consider.

Finding a Shop to Help You

You’ll have a hard time finding a franchised dealership to help you after you’ve removed your emissions. They don’t want to take on the risk of working on decommissioned emission equipment, and they can’t guarantee the work. That means you’ll have to find a qualified independent facility willing to work with you on your own. Even if the engine problem you’re having has nothing to do with your tune or delete, as most of you know, seeing these on the open road can be challenging at best.

Reselling Your Truck

If you ever consider selling or trading in your truck, you will almost certainly run into problems. If you sell it with parts removed, the individual who buys it or takes it in trade will have a legal case against you. You made an unlawful change without informing the customer, and now you’re facing legal (and financial) consequences. You will very certainly have to pay to restore all deleted components to their original configuration. Even taking your truck to an auction doesn’t exempt you from liability, as one forum user pointed out. Law enforcement frequently attends public auctions to guarantee that no illegal activities are taking place. Note:


There are two basic methods in the “economy of emission tuning” that have been developed. The first option is to save money by learning to do it yourself. Because it requires downloading ECM information to your laptop/computer, updating the software, then pushing it back, you should have a foundation in computer science and how diesel engines work if you go this route. True “tuners” do exactly that, and they are subject matter specialists.

These folks, on the other hand, are often hard to discover and are aware of the risks indicated above. They make money in a different way: they sell “tunes” to repair shops. Do you remember the guy who advertised on Facebook and Craigslist that he would do a tune for $1,000? That individual has no idea what he’s doing. He’s buying tuning files from real specialists, marking them up, uploading them to your ECM, and then walking away from you for good.

That’s all we know about eliminating and optimizing your engine. Our recommendation is to avoid it and instead work with a local, experienced repair shop that has access to correct diagnostic instruments and repair information. You’ll be alright if your engine is well maintained and you can locate a qualified repair facility that can precisely troubleshoot emission difficulties. If you can’t find one, we recommend taking advantage of our aftertreatment diagnostics hands-on training program.

What is the penalty for a diesel that has been deleted?

It varies depending on the circumstances, but it might range from a few thousand dollars to millions of dollars. A consumer truck owner convicted of this infraction, for example, will be fined at least $2500 and up to $45,268 per truck. A fine of hundreds of thousands of dollars or even millions of dollars could be imposed on a larger corporation.**

If you are detected with a DPF erase, the EPA will levy the following penalty:

Civil fines for non-compliant vehicles or engines are up to $45,268 per day, $4,527 each tampering event or sale of the defeat device, and $45,268 per day for reporting and recordkeeping violations.

If you’ve been wondering what the EPA fine is for removing your DPF filter, it’s likely that you’ve been suffering less performance and higher fuel usage as a result of your DPF.

Let’s take a closer look at the benefits and drawbacks of having a DPF filter, as well as the potential penalty for not having one.

What is the best way to get rid of diesel emissions?

Some diesel owners are choosing to “remove” these pollution-control components. A diesel deletion entails removing the DEF system, the catalytic converter, and the DPF, and replacing the exhaust with a new one. A tuner will also be required to reprogramme the vehicle’s ECU (engine control unit).

Is it legal for a dealer to sell a truck with a DPF delete?

No, they won’t be able to do that. You can most likely sue and, if it hasn’t been too long, revoke acceptance (return the vehicle.) You may also be eligible to claim under the Fair Business Practices Act for the cost of reinstalling the emissions equipment as well as certain damages.

Is it a good idea to get rid of your diesel?

To put it clearly, any diesel pickup’s emissions equipment should not be removed. It is a federal criminal to remove any factory-installed emissions equipment, regardless of local or state testing regulations. The factory warranty on the vehicle is also void when emissions equipment is removed. Before you say anything, there is no way to prevent a dealer from discovering that emissions equipment has been removed. Even if the hard parts are replaced, the ECM will still show signs of adjustment.

Is eliminating the 6.7 Powerstroke worth it?

The 6.7 Powerstroke has four basic emissions systems: EGR, DOC, SCR, and DPF. The DOC, SCR, and DPF emissions systems, which are all components of the exhaust system, are all deleted using a “DPF delete kit.” The removal of the DPF system is popular since it improves performance, gas mileage, and reliability.

The DPF system is prone to clogging and failure, and replacing it can cost up to $5,000. It also causes a lot of backpressure in the exhaust system, which reduces the turbocharger’s efficiency and reliability. As a result, removing the 6.7 Powerstroke DPF is a superb performance and reliability alternative.

A DPF erase, on the other hand, can be a pain. It is unlawful in terms of emissions, which may cause issues with registration and inspection. You’ll also have to install the delete kit yourself, and you might have difficulties finding anyone willing to work on your truck once it’s been removed.

A delete kit and a tuner are required for deletion. Depending on whether you want a full downpipe-back exhaust system or just the DPF pipe, delete kits run from $250 to 750 dollars. Tunes are roughly $750, therefore a full DPF delete will cost around $1,000-$1,500.

Is it illegal to use DEF erase kits?

It’s not difficult to find someone who can modify or remove the Diesel Exhaust Fluid (or DEF) emissions systems on your agricultural equipment if you look hard enough. Given the openness with which this service is provided, a farmer could be forgiven for thinking DEF alterations are permitted.

They aren’t. The EPA Clean Air Act forbids anybody from removing or rendering inoperable an emission control device on a motor vehicle in the United States. Under a different name, the Canadian Environmental Protection Act, Canada has essentially the same statute.

Even though it is forbidden, DEF tampering occurs. What is causing this, and what are the potential consequences?

Early DEF systems, according to Kevin Rossler, Sales Manager for Markusson New Holland Ag in Regina, could be problematic.

“There were early difficulties in agricultural equipment as it went into Tier-Four emissions or DEF systems,” Rossler explains.

An error signal from a sensor failing at seeding time could cause you to lose power, which is quite inconvenient. As a result, several operators wanted to get rid of their DEF systems or purchase DEF delete kits to avoid having to utilize them.

Interfering with a DEF system can get you in trouble with the law, but that’s not the only danger. It will also nullify the manufacturer’s warranty on the device. When equipment with tampered DEF arrives at a dealership as a trade-in, it must be returned to its original DEF settings before it can be resold. That’s $5,000 to $7,000, according to Rossler’s experience.

He advises equipment owners to let go of any lingering misconceptions regarding DEF, stating that current versions of the technology work significantly more consistently. DEF systems are unlikely to cause problems in the field, but they’re excellent at what they’re supposed to do: regulate emissions from agricultural equipment and help farming keep its good environmental reputation.

Larry Hertz, WEDA’s Regional Vice-President for Canada, adds, “There’s no comparison between early DEF systems and what we have today.”

Today, you could place your face right close to the exhaust pipe and nothing would come out. DEF is required by legislation in order to maintain air quality. Even more reason to leave your DEF alone and let it do its thing.

How long will a 6.7 Cummins engine that has been removed last?

I can personally attest to the fact that I erased 75000 miles ago and have had no problems. On the other side, there are men on here with stock trucks that have logged 300,000 miles and haven’t had any issues. I deleted my truck to make it louder, more like a diesel, and for what I considered to be a decent reliability upgrade. That being said, I recently completed a second-generation S465 conversion that included valve springs, head studs, push rods, a pusher intake, a Billet input shaft, Billet flexplate, triple-disc torque converter, custom-built Billet valve body, and a Billet clutch drum with all aftermarket clutches. However, I also own a 68rfe. I’ll admit that if I were to go out and buy a fresh new truck tomorrow, I wouldn’t hesitate to erase it again.

You can probably do nothing to it and expect it to last 300,000 miles or longer…assuming proper maintenance, minimum lengthy idling, and complete regen cycles. I understand why you want to delete/tune…we all do it for different reasons. There are no egr/mechanical emissions, and it’s a lot of fun.

There have been no issues in the last three years. It performs admirably. Except for the tie rod check, which was well inside the 5 degree requirement, I never went to the dealer.

If you delete, the only problem you’ll have is breaking something because you couldn’t take your foot off the loud pedal. You will have no troubles if you are responsible and take it easy. I drove my ’08 6.7 deleted for 40,000 miles, a ’10 Ford PSD deleted for 30,000 miles, and a ’10 Dodge deleted for 15,000 miles. There were no issues with any of them. Before I destroyed the ’08, the only issue I had was with it. Dodge had the turbo cleaned once before replacing it at 35,000 miles. I deleted the ’08 to avoid having to take it to the shop every 4-6 months for turbo difficulties.

According to these contented owners, a deleted truck is the way to go. After the deletion, the majority of people report having little to no problems.
