The 2020 Cummins delete kit represents a significant modification path for owners of the 6.7-liter Power Stroke engine found in Ford Super Duty trucks. This specific kit is engineered to remove the emissions components mandated by strict EPA regulations for that model year, allowing the engine to breathe more freely. By eliminating the complex web of sensors, mufflers, and particulate traps, the delete creates a platform for optimized performance and simplified maintenance.
Understanding the 6.7L Power Stroke Ecosystem
To grasp the impact of a 2020 delete kit, one must first understand the technological landscape of the 6.7L Cummins. The 2020 model year is particularly complex due to the integration of advanced emissions technology, including dual exhaust gas temperature sensors, a high-pressure oil pump for the exhaust brake, and intricate wiring harnesses. These components, while necessary for compliance, can be a source of ongoing maintenance headaches and potential failure points that a delete kit effectively eliminates.
Performance and Reliability Gains
Removing the emissions hardware reduces backpressure and significantly improves exhaust flow, which translates directly to enhanced horsepower and torque. Drivers often report a noticeable improvement in throttle response, making the truck feel more responsive and alive. Furthermore, the absence of the diesel particulate filter (DPF) and selective catalytic reduction (SCR) system removes the risk of related failures, such as clogged DPFs or malfunctioning NOx sensors, leading to a more dependable powertrain for heavy-duty use.
The Tuning Advantage
A delete kit is not merely a physical removal of parts; it necessitates a corresponding adjustment to the engine control module (ECM) tuning. Without proper tuning, the engine may run inefficiently or trigger diagnostic trouble codes. Most delete kits are sold in conjunction with a custom tune that recalibrates the fuel maps and timing parameters to match the new, unrestricted breathing apparatus. This step is critical for achieving the desired balance of power, efficiency, and drivability.
Legal and Practical Considerations
It is essential to acknowledge the legal implications associated with installing a delete kit. In the United States, tampering with emissions equipment is illegal under federal law, and this modification will cause the vehicle to fail annual inspections in states that require them. Additionally, the warranty for the powertrain will likely be voided by the manufacturer. Potential buyers must weigh the performance benefits against these regulatory and financial consequences before proceeding.
Installation Process and Component Overview
The installation of a 2020 delete kit is a complex mechanical task that generally requires a professional installer. The process involves unbolting and removing the factory exhaust manifolds, turbocharger, and associated piping for the emissions components. The kit typically includes a new exhaust manifold designed to accommodate the wide-band O2 sensor and a downpipe that bypasses the previously mentioned emissions devices. Attention to detail during installation is vital to prevent exhaust leaks and ensure proper alignment.
Comparing Alternatives for the 2020 Model
While the delete kit is the most comprehensive solution, some owners explore alternatives like deleting only the DPF or EGR systems. However, these partial deletions often yield less dramatic results and can still trigger warning lights. The 2020 Cummins delete kit offers a holistic approach, providing a clean slate for the engine. This allows the vehicle to operate without the nagging alerts related to emissions sensor discrepancies that plague partial deletion methods.
Long-Term Ownership Experience
Owning a truck with a delete kit installed shifts the focus from passive compliance to active maintenance. Owners save money by bypassing the costly repairs associated with the after-treatment system, such as DPF replacements or SCR injector cleaning. The simplicity of the powertrain makes troubleshooting easier, as there are fewer components to diagnose when a problem arises, ultimately leading to a more straightforward and cost-effective ownership experience over the life of the vehicle.
