Hey there, gearhead. Feeling bogged down by your diesel exhaust fluid requirements? Sick of having to fill up that pesky DEF tank every few thousand miles just to keep your check engine light from coming on? There’s an easy solution for you. A DEF delete kit can free your diesel engine from the shackles of emissions systems and let your truck run like it was meant to.
DEF fluid, also known as AdBlue, is required for most modern diesel engines to meet emissions standards. While reducing emissions is important for the environment, DEF fluid requirements are a pain for diesel owners and truckers alike.
Constantly having to monitor DEF levels and fill up the tank cuts into valuable time and money. Not to mention the hassle of the warning lights and derate modes that kick in if your DEF tank runs dry.
A DEF delete kit provides freedom from all that. By eliminating the components that rely on DEF, like selective catalytic reduction filters, you can wave goodbye to the frustrations of diesel exhaust fluid for good.
Your diesel engine will make full power again and you’ll never have to sacrifice another coffee break to run out and fill your DEF tank. It lets your diesel run the way it was meant to – without restraints and without constantly needing an emissions-approved refill. Give your truck a clean start and a new lease on life with a DEF delete kit.
What Is a DEF Delete Kit?
This is designed to remove the Diesel Exhaust Fluid system from vehicles with diesel engines. It is also known as AdBlue and is used to lower nitrogen oxide emissions from diesel vehicles to meet emissions standards.
How It Works
The DEF delete kit typically consists of a tuner module that connects to your vehicle’s engine control unit (ECU) and a downpipe that replaces the factory catalytic converter and DEF injector. The tuner module modifies or ‘tunes’ the ECU to eliminate the need for the DEF system.
Once installed, the DEF delete kit bypasses the DEF injector and DEF tank, allowing you to remove them. No more refilling the DEF tank or worrying about warning lights coming on! The modified downpipe also provides performance improvements like increased throttle response.
A DEF delete kit may be appealing if you want improved performance, hate dealing with the DEF system, or live in an area without emissions testing. However, deleting the DEF system is illegal for on-road use in the US and Canada since it tampers with the vehicle’s emissions system. It will also void your vehicle’s warranty.
Is It Right For You?
If staying fully emissions-compliant or keeping your vehicle warranty intact are top priorities, a DEF delete kit is not recommended. But for off-road or competition use, a DEF delete can provide some nice benefits. As with any vehicle modification, do thorough research to determine if the pros outweigh the cons for your needs and ensure you understand all legal implications.
Why Install a DEF Delete Kit on Your Vehicle?
Installing it on your vehicle has some major benefits.
First, it improves performance. Without the DEF system, your engine has fewer restrictions and can reach optimal power. Many owners report an increase of 50-100 horsepower after removing the DEF system.
Second, it reduces maintenance costs. The DEF fluid, diesel exhaust fluid, has to be refilled regularly. By removing the DEF system altogether, you no longer have to pay for expensive DEF refills or worry about warning lights coming on when the fluid is low.
Fewer Repairs Needed
DEF systems are prone to failure and expensive repairs. Sensors, injectors, and pumps can malfunction, costing thousands to fix. A DEF delete kit eliminates these components so you avoid costly repairs down the road.
Increased Reliability
It reduces emissions but also reduces reliability. With more parts, more things can go wrong. Removing the DEF system improves the overall reliability and dependability of your vehicle.
If you want a cleaner, more powerful, and dependable ride, installing a diesel exhaust fluid delete kit is the way to go. Your engine will breathe easier and your wallet will thank you. Who knew fewer emissions could feel so good?
How to Choose the Best DEF Delete Kit
Choosing the right DEF delete kit for your vehicle depends on a few factors. The two main types are plug-in modules and flashing tuners.
Plug-In Modules
Plug-in modules are simple to install. You just plug them into your vehicle’s OBD2 diagnostic port, typically located under the dashboard. These modules trick the sensor into thinking the DEF tank is full so the warning lights turn off.
Popular, inexpensive options for most vehicles include the Pedal Commander Throttle Response Controller and the BD Diesel Performance DEF Delete Module.
Flashing Tuners
For a more permanent solution, consider a flashing tuner. These reprogram your vehicle’s ECU to fully disable the DEF system. Installation is more complex, as it requires connecting the tuner to your OBD2 port and uploading a custom tune.
However, the DEF system is disabled even after the tuner is removed. Popular brands for GM, Ford, Dodge, and Jeep include DiabloSport, SCT, and Bully Dog.
No matter which type you choose, make sure it’s compatible with your specific vehicle’s make, model, and engine. Carefully follow the instructions for installation and any troubleshooting tips to avoid error codes or warning lights. Once installed, your DEF gauge should read normal levels and any warning lights related to the DEF system should turn off.
Conclusion
So there you have it, everything you need to know about DEF delete kits to get your diesel truck running clean and mean. By removing the cumbersome DEF system from your vehicle, you’ll experience a boost in power and performance along with greater reliability.
While emissions regulations aim to improve air quality, for many diesel owners the hassle and cost of DEF fluid and frequent fill-ups just don’t seem worth it. With a DEF delete kit, you can have the best of both worlds – compliant emissions when needed but the freedom to optimize your engine’s potential whenever you want.
What are you waiting for? Give your diesel a new lease on life and your wallet a break with an easy-to-install DEF delete kit. The open road is calling!
