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

DEF Delete Kit for Jeep Gladiator 2020-2023

The 2020, 2021, 2022, 2023 Jeep Gladiator DEF delete kit is an All-in-One bundle for supported Gladiator models equipped with the 3.0L EcoDiesel engine. It combines professional Bench-Flash Tuning with a vehicle-specific stainless steel race pipe designed around the Gladiator’s longer wheelbase and unique exhaust routing. Buyers can choose Stock Power, Stage 1 (+30 HP), or Stage 2 (+50 HP) when configuring the package.

The system replaces the restrictive factory DPF/SCR exhaust section and recalibrates the ECU for the modified emissions configuration. DPF regeneration is eliminated for the removed filter, exhaust flow is improved, and the selected tune can provide additional horsepower and torque without requiring a handheld tuner to remain in the vehicle.

Why Choose This Kit

• Gladiator-specific hardware - the race pipe is designed specifically for the truck’s longer chassis and exhaust routing.
• Three tune options - Stock Power, Stage 1 (+30 HP), or Stage 2 (+50 HP).
• Professional Bench-Flash Tuning - the original ECM is programmed directly for the selected configuration.
• No physical EGR removal required - EGR-related operation is handled through tuning while the hardware remains installed.
• Complete matched package - custom tuning and the required exhaust components are supplied for the same 2020-2023 EcoDiesel platform.

Vehicle Compatibility

The Jeep Gladiator DEF delete kit is not interchangeable with the Wrangler version even though both models use the 3.0L EcoDiesel. The Gladiator has different exhaust geometry because of its longer wheelbase and pickup bed, so it requires its own pipe design. Current product information also notes that Rubicon applications use this Bench Flash solution; non-Rubicon fitment should be confirmed before ordering.

Kit Components

• Bench-Flash ECU Tuning - the original ECU is removed from the vehicle and programmed directly with the selected emissions-off calibration.
• Custom Tune - available as Stock Power, Stage 1 (+30 HP), or Stage 2 (+50 HP). The tune modifies the required DPF, DEF, and EGR-related ECU strategies while retaining normal engine control.
• Gladiator-Specific Race Pipe - replaces the factory DPF/SCR exhaust section and reduces restriction and backpressure. It is built specifically for Gladiator fitment rather than adapted from the Wrangler.
• Clamps and Installation Hardware - provide the required connections for the replacement exhaust section.

The Jeep Gladiator Ecodiesel DEF delete kit does not include a physical EGR Delete Kit. The EGR valve, throttle valve, MAF sensor, MAP sensor, and EGT sensors remain installed unless specific tuning instructions state otherwise. The DEF tank and DEF-related sensors should also remain in place according to the current installation notes.

Tuning & Performance

The Jeep Gladiator 3.0 DEF delete kit uses a fixed Bench-Flash calibration rather than SOTF. The desired tune is selected before the original ECM is programmed.

Stock Power retains the factory horsepower level while adapting the ECU to the changed emissions system. Stage 1 adds 30 horsepower, while Stage 2 adds 50 horsepower for customers looking for greater performance.

Removing the factory DPF/SCR section eliminates regeneration for the removed filter and allows freer exhaust flow. The modified setup can also provide improved throttle response and stronger torque delivery. Actual fuel economy, power feel, and reliability depend on vehicle condition, tire size, gearing, terrain, modifications, and driving style.

Installation

Before Bench-Flash programming, the vehicle should be operating correctly in its factory configuration. Complete a full DPF regeneration when required, resolve active DPF/DEF warnings or fault codes, and return any previously tuned ECM to stock before removing it from the truck. The original ECU is then shipped in for programming with the selected Stock, Stage 1, or Stage 2 tune.

After the programmed ECU is returned, reinstall it and confirm correct operation before completing the hardware installation. Remove the factory DPF/SCR section and install the Gladiator-specific race pipe, while leaving the EGR system, throttle valve, MAF, MAP, EGT sensors, DEF tank, and DEF sensors in place. Basic hand and exhaust tools are sufficient for experienced DIY owners, while unresolved diagnostic problems or non-factory modifications may require professional support.

Ordering Information

Before ordering, confirm a supported 2020-2023 Jeep Gladiator EcoDiesel 3.0L and choose the desired calibration: Stock, Stage 1 (+30 HP), or Stage 2 (+50 HP). The Bench-Flash Tuning service uses the vehicle’s original ECU rather than a separate handheld tuner.

After purchase, a prepaid shipping label is provided for ECM shipment. The label is valid for 60 days, and the current product information states that the ECU is typically programmed and shipped back within 4-6 business days after it is received, with return transit generally taking another 2-3 business days.

Hardware and ECM service may be handled separately, so package components can arrive at different times. Confirm the tune option and vehicle fitment before the ECU enters programming because custom calibration and other vehicle-specific products may have return restrictions once processing has begun.

This package is intended for lawful off road, racing, or competition use.
