How much extra MPG can I realistically expect with this 2019-2021 6.7 Cummins delete kit?

By removing the restrictive DPF and the fuel-heavy "Regen" cycles, most owners see a consistent increase of 4-6 MPG . This makes the 6.7 cummins delete kit with tuner one of the few performance upgrades that actually pays for itself over time by significantly reducing your cost-per-mile during daily driving or long-haul towing.

Will I need to drain the coolant to install the EGR delete on my 2019+ Ram?

While our EGR Valve & Cooler Delete Kit is designed for a precise fit, we do recommend a partial coolant drain to ensure a clean installation of the bypass plates. This prevents any air pockets from forming in the CGI head's cooling passages, ensuring your 5th Gen Cummins maintains optimal thermal management after the delete.

Can I still use my factory exhaust brake after installing the 4" Race Pipe?

Yes! The tuning included with this 2019-2021 6.7 cummins delete kit retains full functionality of the factory VGT (Variable Geometry Turbo) exhaust brake. You will still have the same aggressive stopping power when hauling heavy loads, but with significantly lower exhaust backpressure and a much deeper, more aggressive tone.

Is the tuner in this kit compatible with future engine modifications?

Absolutely. The digital tuner provided is not a "one-and-done" device. It is a robust platform that supports multiple power levels (from Fuel Economy to Race). If you later decide to upgrade your turbo or injectors, the tuner can be updated with new calibrations, making it a future-proof investment for your 2022 6.7 cummins delete kit or performance build.

Does this kit cause a "Limp Mode" or permanent Check Engine Lights?

Not at all. The primary purpose of the 6.7 cummins delete kit with tuner is to communicate with the ECM to prevent "Limp Mode" entirely. By utilizing the included SGW bypass, the software "handshakes" with your truck to disable all emission-related fault codes, ensuring a clean dashboard and full power delivery at all times.

Soot-Free Engine Longevity Protocol: Moving beyond mere power gains, this kit targets the 2019+ specific vulnerability of hydraulic lifters. By physically cutting off EGR circulation, it ensures 100% fresh air enters the manifold. This prevents oil acidification and abrasive soot buildup, shifting your engine's future from "costly repairs" to "preventative longevity."
CP4 Pump Stress-Relief Strategy: Engineered specifically for the fragile CP4 pumps found in 2019-2020 models. Our paired Tuner software optimizes injection timing to eliminate high-pressure pulses during regen-cycles. This effectively "defuses" the mechanical stress on your fuel system, acting as a digital insurance policy for your high-pressure pump.
Full-Spectrum Digital Pilot Monitoring: The included digital interface is more than a tuning tool; it’s an industrial-grade cockpit. It unlocks over 20 critical parameters hidden by the factory dashboard—such as real-time Rail Pressure, Boost curves, and Transmission slip. This "Data Visibility" allows you to anticipate issues before they happen, commanding your 6.7L Cummins with professional-grade precision.

For the 2019-2021 6.7L Cummins, this represents an era of peak factory power, but also the peak conflict between complex emission components and hardware reliability. While these years introduced the high-strength CGI block and hydraulic lifters, the restrictive emission systems have become the "Achilles' heel" of its long-term durability.

1. The "Self-Destruction" Pressure of the CP4 High-Pressure Fuel Pump

2019-2021 Specific Pain Point: During this period, Cummins replaced the ultra-reliable CP3 with the CP4.2 fuel pump. This design is hyper-sensitive to fuel lubricity. The frequent Regen cycles of the emission system force the engine to run under sustained high heat and load. If lubrication fails, internal metal shavings from the pump can instantly contaminate the entire fuel system, leading to repair bills exceeding $10,000.
The Salvation: By installing a 6.7 Cummins delete kit with tuner, we don't just remove physical restriction; we optimize fuel injection timing via software. By lowering the overall thermal load on the engine and reducing high-pressure pulses during extreme Regen modes, we effectively "defuse" the stress on this ticking time bomb.

2. The Fatal Encounter: Hydraulic Lifters vs. Carbon Soot

2019-2021 Specific Pain Point: The 2019+ engines introduced self-adjusting hydraulic lifters. While they eliminate the need for manual valve adjustments, they are exceptionally sensitive to oil purity. The factory EGR system recirculates massive amounts of carbon-heavy exhaust into the intake. These abrasive particles find their way into the engine oil, leading to premature wear, sticking, or catastrophic valve train failure.
The Salvation: Our EGR Valve & Cooler Delete Kit achieves complete physical isolation. By ensuring your engine breathes 100% fresh air, your oil no longer turns pitch black prematurely from soot. This provides a pristine operating environment for the expensive hydraulic components of the 2019-2021 models.

3. The 5th Gen Exclusive Electronic Lock (Security Gateway)

2019-2021 Specific Pain Point: All models after 2018.5 are equipped with a Security Gateway Module (SGW). This acts as an electronic wall, blocking most standard tuning tools from modifying the ECU. For 2019-2021 owners, hardware installation is useless without the protocols to clear the resulting fault codes.
The Salvation: This is a true All-in-one solution, including a custom SGW Bypass Cable. This "key" allows the tuner to communicate directly with the ECU, permanently clearing DPF/EGR-related trouble codes. Your truck’s computer and hardware will work in perfect harmony without the annoyance of a "Check Engine" light.

4. The Short-Life Prophecy of the VGT Turbo

2019-2021 Specific Pain Point: To meet emission standards, the Variable Geometry Turbo (VGT) in these years operates at extreme temperatures. The massive backpressure created by the DPF causes carbon soot to "bake" onto the turbo vanes (coking), leading to sticking or sluggish response—one of the most common expensive warranty claims for 2019-2021 owners.
The Salvation: The 4" Race Pipe completely removes the "cork" in your exhaust. This sudden drop in backpressure allows exhaust gases to exit much faster, reducing Exhaust Gas Temperatures (EGTs) by approximately 400°F. This doesn't just let the turbo breathe; it prevents vane failure caused by high-heat carbon buildup, significantly extending the life of your turbocharger.

Product Description - Part II: Installation & Technical Comparison

Seamless Integration — Precision Engineering for the DIY Enthusiast

Installing a performance kit on a 5th Gen Ram shouldn't feel like rocket science. Our 2019-2021 specific kit is engineered to respect the tight tolerances of the modern Cummins chassis, ensuring that "All-in-One" actually means "Everything-You-Need."

1. 100% Bolt-On Installation: No Cutting, No Welding

Chassis-Specific Fitment: Unlike "universal" 4-inch pipes, our 4" Race Pipe is precision-bent to follow the exact contours of the 2019-2021 Ram 2500/3500 frame. It utilizes the factory rubber hangers and flange locations.
Sensor-Ready Design: We’ve pre-welded bungs for your factory Exhaust Gas Temperature (EGT) sensors. You don't need a drill; you just need a wrench.
Modular EGR Delete: The EGR Valve & Cooler Delete Kit includes laser-cut bypass plates that seal perfectly against the CGI head, preventing the coolant leaks common with inferior, thinner plates.

2. Hard Data: Stock vs. Unleashed (2019-2021 Benchmarks)

We don't just promise "better" performance; we deliver measurable results. Below is a real-world comparison of a stock 2019-2021 6.7L Cummins versus one equipped with our 6.7 cummins delete kit with tuner.

Performance Metric	Stock Configuration	Deleted & Tuned	Net Gain / Improvement
Torque Output	850 - 1,000 lb-ft	1,050 - 1,250+ lb-ft	+25% Towing Power
Exhaust Gas Temp (EGT)	1,400°F+ (In Regen)	900°F - 1,050°F	400°F Reduction (Turbo Safety)
Fuel Economy (MPG)	12 - 14 MPG (Avg)	17 - 21 MPG	+4-6 MPG Increase
Oil Contamination	High (Soot Injected)	Near Zero Soot	2x Engine Oil Life

3. The Gateway Bypass: The 5-Minute Electronic Handshake

The biggest hurdle for 2019+ trucks is the electronic firewall. Our kit simplifies the "un-hackable":

Plug-and-Play: The included SGW bypass cable plugs directly into the factory harness behind the dash.
Total Control: Once connected, your tuner gains full authorization to communicate with the ECM, allowing for a 5-minute software flash that permanently silences the "Exhaust System Full" and "See Dealer" warnings.

Conquer All Terrains — Reclaiming the Value of Your Cummins

This All-in-One kit is more than just a hardware swap; it’s a total liberation of the raw industrial power inherent in the 2019-2021 6.7L Cummins. Whether facing extreme climates or heavy-duty tasks, it puts control back in your hands.

1. Survival in Extreme Scenarios

High-Load Towing & Long Grades:
The Problem: Stock emission systems generate extreme heat, triggering a "De-rate" mode that leaves you underpowered on steep inclines.
The Solution: With the 6.7 cummins delete kit with tuner, exhaust flows freely. Even while towing 15,000+ lbs in mid-summer heat, your engine stays cool, maintaining peak torque without the fear of EGT-induced shutdowns.
Cold Weather & Extended Idling:
The Problem: In freezing climates, idling is necessary for warmth, but it quickly clogs the DPF with soot.
The Solution: After removing the DPF, your truck is no longer "idling-restricted." Start and go regardless of the temperature, ending the need for forced highway runs just to clear a "soot-clogged" filter.

2. The Ultimate Reliability for Overlanding

Eliminating "DEF Anxiety": Finding high-quality DEF in remote areas or during long cross-country hauls can be a nightmare. Poor quality DEF leads to immediate sensor failure and limp mode.
The Value: After the delete, your truck depends only on diesel fuel. This simplified mechanical structure provides the "certainty" needed for off-grid adventures and heavy-duty work.

3. Why 2019-2021 Owners Choose This Kit

Protecting Resale Value: In the diesel community, a 2019-2021 Cummins that has been protected from soot-related lifter wear and CP4 stress is far more desirable than a "stock" truck with a ticking repair clock.
Real-Time Data Command: The included Tuner display provides high-fidelity data that factory gauges miss—monitor your Boost, Rail Pressure, and Transmission Temps in real-time, commanding your 6.7L beast with precision.

Final Verdict: Don't let 2019-era emission regulations dictate your truck's lifespan. Unlock the 2019-2021 6.7 cummins delete kit and experience the legendary Cummins durability as it was meant to be.
