Full DEF Delete Kit w/ Bench-Flash Tuning | Jeep Wrangler EcoDiesel 3.0L | 2020-2023

DEF Delete Kit for Jeep Wrangler 2020-2023

The 2020, 2021, 2022, 2023 Jeep Wrangler DEF delete kit is an All-in-One bundle for supported Wrangler EcoDiesel models with the 3.0L diesel engine. It combines vehicle-specific Bench-Flash Tuning with a hand-crafted 3-inch race pipe designed specifically for the Wrangler exhaust layout. The package removes the factory DPF and SCR exhaust section while recalibrating the ECU for the modified emissions system.

Unlike earlier EcoDiesel platforms that can use physical EGR removal hardware, this application keeps the EGR system, throttle valve, MAF, MAP, and EGT sensors installed. The calibration electronically handles the required emissions-off functions while the replacement pipe improves exhaust flow and removes the restrictive particulate-filter section.

Why Choose This Kit

• Wrangler-specific Bench-Flash Tuning - calibration is programmed directly into the original ECM for the selected setup.
• Three fixed tune options - choose Stock, Stage 1 (+30 HP), or Stage 2 (+50 HP).
• Model-specific race pipe - the Wrangler pipe is built for its exhaust routing and is not interchangeable with the Gladiator version.
• No physical EGR removal required - the EGR hardware stays installed while the applicable function is handled electronically.
• Complete matched package - tuning and exhaust hardware are selected for the same 2020-2023 EcoDiesel platform.

This Jeep Wrangler DEF delete kit provides the core components required for the supported off-road configuration without adding unnecessary EGR hardware that is not part of the installation procedure.

Vehicle Compatibility

Current product information identifies the Bench Flash application specifically with supported Wrangler EcoDiesel configurations. Wrangler and Gladiator use different exhausts and pipe geometry, so hardware should never be selected only by engine and year. Non-standard trims, previous tuning, or modified exhaust systems should be verified before ordering.

Kit Components

• Bench-Flash ECU Tuning - the original ECU is removed and sent in for direct programming. The selected calibration modifies engine management for the new exhaust configuration.
• Custom Tune - available as Stock, Stage 1, or Stage 2. The tune adjusts diagnostics, fueling, boost management, torque delivery, and the emissions-related strategies required for the modified system.
• 3" Hand-Crafted Race Pipe - current product information identifies a T-304 stainless pipe built specifically for the Wrangler. It replaces the factory DPF and SCR section and uses model-specific routing and mounting points.
• Clamps and Installation Components - provide the required connections for the replacement exhaust section.

A physical EGR Delete Kit is not part of this package. The EGR valve and supporting sensors remain installed, which is an important difference from many older EcoDiesel delete parts packages.

Tuning & Performance

The Jeep Wrangler Ecodiesel DEF delete kit uses fixed Bench-Flash tunes rather than an OBD handheld tuner or SOTF system. Select the desired stage before the original ECM is programmed.

Stock retains factory-level horsepower while adapting the ECU to the modified exhaust. Stage 1 offers an additional 30 horsepower, while Stage 2 provides 50 horsepower over the stock level on supported applications.

Removing the restrictive DPF/SCR section eliminates regeneration for the removed filter and allows freer exhaust flow. The higher-power tunes can also provide improved throttle response and enhanced torque delivery. Fuel economy may change, but actual results depend on engine condition, tires, gearing, driving style, terrain, and selected calibration; fixed mileage gains should not be guaranteed.

Installation

The Jeep Wrangler 3.0 DEF delete kit requires the tuning procedure to be completed before the emissions hardware is removed. Start with the Wrangler in its original configuration, complete a full DPF regeneration if required, clear existing DEF/DPF countdowns and warning codes, and return any previously tuned ECU to the factory calibration before removing it for Bench Flash service.

Ship the original ECM using the supplied label. Once the module is flashed and returned, reinstall it and confirm that the Jeep starts and runs correctly before installing the race pipe. After successful verification, remove the DPF/SCR exhaust section and install the Wrangler-specific pipe. Keep the EGR, throttle valve, MAF, MAP, and all EGT sensors installed as directed by the current procedure.

An experienced DIY owner can perform the ECU removal and mechanical installation with basic hand and exhaust tools. Professional support is recommended when the vehicle has unresolved codes, previous aftermarket tuning, damaged hardware, or uncertain fitment.

Ordering Information

Before purchase, confirm a supported 2020-2023 Jeep Wrangler 3.0L EcoDiesel and select Stock, Stage 1 (+30 HP), or Stage 2 (+50 HP). This package uses a Bench Flash service rather than a tuner delivered with downloadable tunes, so the vehicle’s original ECM must be shipped in for programming.

After purchase, a prepaid shipping label is provided for the ECM and remains valid for 60 days. Once the module arrives, Bench Flash processing is approximately 4-6 business days, followed by about 2-3 business days for expedited return shipping. Processing can take longer during busy periods because each calibration is validated before the ECU is returned.

Bench flash services, custom calibrations, race pipes, delete components, and other customer-specific products may become final sale once programming or production has started. Eligible physical products must otherwise meet the store's current 30-day return and RMA requirements.
