SuncentAuto DPF Delete Kit Review – Power Gains & Real-World MPG

Diesel truck owners are always looking for ways to improve power, throttle response, fuel economy, and overall driving performance. One modification that receives considerable attention in the diesel community is the DPF delete. SuncentAuto offers a range of diesel exhaust products designed for different truck platforms, including Powerstroke applications.

But does a SuncentAuto DPF delete kit actually deliver meaningful gains in power and fuel economy? And how much should truck owners expect to see in everyday driving?

This review looks at the advertised benefits, potential performance improvements, fuel-economy claims, and important considerations before making a decision.

What Is a DPF Delete Kit?

A diesel particulate filter, or DPF, is part of a modern diesel truck’s emissions-control system. Its primary purpose is to capture soot and particulate matter from the exhaust before those pollutants reach the atmosphere.

A DPF delete kit replaces or removes the factory DPF-related exhaust components with aftermarket exhaust hardware. SuncentAuto describes its delete-pipe products as free-flowing alternatives designed to reduce exhaust restriction and improve flow. The company lists applications for several major diesel platforms, including Ford Powerstroke, Dodge/Ram Cummins, Chevrolet/GMC Duramax, and EcoDiesel models.

SuncentAuto provides products geared towards the Powerstroke platform, which is the platform that Powersports vehicles use. The packages range from the DPF delete pipe, EGR parts, CCV equipment, exhaust parts, through to tuning equipment.

What Performance Gains Does SuncentAuto Advertise?

The main reason why exhaust mods are popular with owners of diesel engines is that they help with performance.

SuncentAuto says that its DPF delete products deliver around 20 more horsepower and 25 more lb-ft of torque. However, this could vary based upon the truck, engine tuning, additional modifications, and driving environments.

The company also provides a bit more extensive performance stats on some of the full Powerstroke packages. Its information for a 2017-2019 6.7L Power Stroke, for instance, compares stock and modified setups and reports increased acceleration and exhaust temps. These are manufacturer-provided testing claims and are not 3rd party laboratory results.

That distinction matters. A single delete pipe won’t always mean a certain uptick in horsepower. Modern diesel engines rely heavily on electronics for electronic calibration, turbocharger response, fuel delivery, and emissions-system controls. Therefore, the final product is not just a function of one exhaust component, but a function of all of the exhaust components.

Throttle Response Can Be More Noticeable Than Peak Horsepower

The most important distinction for many diesel drivers might not be the dyno sheet number.

If exhaust is restricted, there could be a shift in engine response when accelerating. The driver might experience faster throttle response, improved acceleration when operating under load, and improved exhaust characteristics.

SuncentAuto states that the benefits of its 6.7L Powerstroke delete packages are improved throttle response and overall power output.

But perceptions of performance vary widely. A truck’s acceleration is affected by its tires, its gearing ratio, the elevation, load weight, transmission tuning, fuel quality, and tuning. A lightly loaded truck driving through town can make a completely different impression than a heavy-load truck towing a trailer.

SuncentAuto DPF Delete Kit and MPG

The fuel economy aspect of the delete kit is probably the most appealing.

The general DPF-delete category on SuncentAuto’s products promises up to 23% fuel savings, and the company advertises fuel-economy improvements on its DPF-delete products.

Some of the 6.7L Powerstroke product pages boast even more impressive numbers, such as a stated 28% increase in MPG.

These figures are only what they claim to increase by, not what they will actually get in real-world driving.

Actual mileage will vary depending on driving conditions and your driving style. Fuel Economy can be significantly affected by highway cruising, towing, stop-and-go traffic, engine tuning, winter weather, tire pressure, and vehicle load. So, it is incorrect to think that any truck will automatically become 20% or more without a truck delete kit.

If you want to compare, track fuel usage over several tanks before and after the change, and keep driving conditions as consistent as possible.

Why Exhaust Flow Matters

A factory diesel emissions system consists of a number of components that help to reduce emissions. This is especially relevant regarding the DPF since it will collect particulate matter from diesel exhaust.

When it comes to performance, aftermarket exhaust parts can also be created to offer less restriction. SuncentAuto claims that its delete pipes are corrosion-resistant stainless steel pipes and are engineered to allow for more unrestricted exhaust flow.

The more unrestricted, the better engine response, and it may be used in conjunction with other performance modifications. But, exhaust flow should always be viewed in the context of the whole engine system and not as a standalone upgrade.

What Comes With a 6.7 Powerstroke Delete Kit?

Contents are dependent on model year and package.

For instance, SuncentAuto’s 6.7L Powerstroke packages can include a DPF delete pipe, EGR-associated parts, and a tuner. One listed package for 2015-2016 also features a Mini Maxx tuner, a 4-inch exhaust race pipe style exhaust, and an EGR delete kit.

A 2011-2019 package will also come with a 4-inch DPF and catalytic-converter delete pipe, EGR delete equipment, and a CCV/PCV reroute system with a catch can.

This is because buyers should never select a kit based on just the engine’s name. All model year, truck configuration, previous modifications, and package contents must match.

Is the MPG Improvement Worth It?

If an off-road or competition vehicle allows for such changes, better fuel economy might be one of several factors.

But fuel savings should not be considered a given. Even SuncentAuto’s published MPG figures are claims relating to specific products and/or testing or calculating procedures and are not necessarily representative of the results of any individual truck.

If you’re considering the modification, you should figure out the fuel savings, installation costs, necessary tuning, maintenance, and possible inspection or warranty implications before investing in it.

Important Legal and Emissions Considerations

This is the most crucial issue to address whenever deleting a DPF comes up.

Emissions system changes can make a vehicle noncompliant with emissions standards and, depending on jurisdiction, illegal to operate on public roads. According to SuncentAuto, its delete products are for off-road, racing, or competition only and are not for vehicles subject to emission regulations, typically those on public roads.

Also, the company points out, modified vehicles may not pass emissions or State inspection tests, and customers must adhere to local, state, and federal regulations.

Therefore, the owners should verify the regulations that apply prior to buying or installing emissions-related equipment. A modification that works well for a closed-course or a vehicle used exclusively for off-road use may not be right for a vehicle driven daily on a street.

Final Verdict

SuncentAuto’s DPF delete products aim to be performance exhausts for the performance-minded diesel fans who desire better exhaust flow and engine response. The company’s published information touts gains in horsepower, torque, and fuel economy, and the company’s 6.7L Powerstroke packages are a collection of exhaust hardware and other tuning solutions.

The claimed MPG and power numbers should be viewed as attainable, not actual. The actual performance of a truck will depend on the condition, engine calibration, modifications, and driving environment of the truck.

For owners researching the available hardware, SuncentAuto’s DPF delete kit range provides options across several diesel platforms, while its 6.7 Powerstroke delete kit collection focuses specifically on Ford’s 6.7L Powerstroke applications.

In the end, it depends on the use of the truck, expectations of performance, and, most importantly, if the modification is allowed in the area where the truck will run.
