Duramax DPF Delete Problems

The Duramax needs a larger air intake, as well as for the exhaust, so it can generate more output or power.

When you tune it, this manipulates important engine commands such as boost, fuel, and timing. When there is stock emissions equipment used, custom tuning can generate the same power.

However, there are things that can occur when you delete your DPF. In fact, the DPF does not show much negative effects on the horsepower. But for others, this may be an issue.

The following are common Duramax DPF delete problems that you may want to be aware of.

1. Void the Warranty

When a DPF delete is done, this voids the warranty of your vehicle automatically. Eventually, it works the issues out on its own. Moreover, your truck is likely to have a longer lifespan once issues linked with the DPF have been eliminated completely.

There are also a few dealerships that say there is no negative consequence to worry about if you delete the DPF. Yet, it is worth studying your options well since there are still some problems that may arise. And it gets worse once your warranty has been voided already.

2. Delete and Not Tune

Now, there is a complete emissions system hooked up to your truck’s computer. Once you remove the DPF without tuning your vehicle first, this causes it to enter into a limp mode, which means you cannot use it at all.

3. Legal Issues

Emissions equipment is placed in vehicles to make sure they are compliant with the legal emission requirement. On the other hand, once the equipment is removed through a delete, this pushes the emissions to illegal levels.

As a result, this makes it not legal to perform a delete. And you run the risk of being prosecuted under law in case you are caught doing it. You will only be permitted to do it when the vehicle is used for the purpose of off road dragging.

Understanding The Duramax DPF Delete

The Diesel Particular Filter or DPF is used for removing soot from your engine. This is a built-in feature in your engine. Then, the soot that has been removed is maintained in a container with compartments shaped like a honeycomb. Over time, the compartments become clogged up.

Thus, this restricts the exhaust, which then leads to a regeneration cycle to arise. This means that the diesel fuel burns off all the soot, which is then forced out of your exhaust system.

Once the DPF is damaged, it can be quite expensive to fix. Moreover, a faulty DPF reduces the performance of your engine. This is why it makes sense to delete the DPF. Truck owners also may choose to do a DPF delete to improve the performance of their vehicle.

But then again, there are some issues involved when it comes to doing a DPF delete. After all, diesel soot has an oily and dirty quality.

Then, the build-up of carbon from your exhaust clogs up the exhaust gas recirculation valve, DPF, and the sensors.

Many vehicle owners, however, report a drop in the performance of their vehicles by a significant level. This is why there is a need to replace or clean their emissions equipment. And to save money, an option to delete such components becomes something to consider.

During a DPF delete, the DEP system is taken out. Then, the DPF and catalytic converter are removed before the installation of a new exhaust.

Next, a reprogram of the engine control unit is done using a tuner. This component also replaces the OEM software with a brand new program that controls your engine’s fuel delivery and timing.

In addition to these functions, your tuner also recalibrates the ODS system, which gauges the engine operating parameters. Hence, it ensures that there are zero codes linked with emissions due to any missing components.

There have been reports of a DPF delete promoting better performance, enhancement in torque and fuel economy. Yet, there are also some issues to consider such as voiding the warranty, putting the vehicle in limp mode, and the issue of it being illegal in certain places.

But at the same time, some positives can be expected such as increased reliability of your vehicle. When there is no more exhaust emissions recycled, this means there is a reduced change of build-up or clogs.

Additionally, diesel engines that have no DPF have a better sound. There is also no need for a more frequent oil change since your engine oil stays cleaner for longer.

And lastly, this improves fuel economy. This applies when your vehicle comes with a Diesel Exhaust Fluid, which is injected into your truck’s exhaust system. It burns away soot that builds up inside the airways.

Overall, it costs a certain amount to do a Duramax DPF delete. Here are potential expenses to consider:

  • Tuning – $700
  • PVC Reroute – $50
  • New Exhaust – $50
  • Bloker Plate – $15
  • Cold slide and Y bridge – $700
  • Lift Pump – $600

So you are looking at paying over $2000 for a complete delete, although it varies depending on where you are and other costs involved.

Final Thoughts

A Duramax DPF delete may seem promising because of the numerous benefits it claims to offer. However, there are still some people who are not so convinced about these benefits since there are some issues to think about such as voiding the warranty, among other things.

So, it makes perfect sense to think through your options first then decide on what works best for your vehicle that will give you the best return on your investment for a reasonable cost upfront.
