Full DEF Delete Kit w/ EFI Live AutoCal V3 | Ram Cummins Cab & Chassis 6.7L | 2013-2018

2013-2018 RAM 6.7 Cummins Cab and Chassis DEF Delete Kit

The 2013-2018 DEF delete kit for 6.7 Cummins C&C is an All-in-One bundle designed specifically for RAM 3500, 4500, and 5500 Cab & Chassis trucks equipped with the 6.7L Cummins diesel engine. It combines the EFI Live AutoCal V3 tuner, vehicle-specific custom calibration, EGR valve and cooler removal hardware, and a Cab & Chassis-specific exhaust solution.

This full package is built around the different exhaust routing, frame configuration, and calibration requirements of commercial C&C models. It removes the factory DPF, DEF/SCR, and EGR systems, eliminates regeneration of the removed particulate filter, and matches the mechanical changes with a fixed engine tune developed for the modified truck.

Why Choose This Kit

• Cab & Chassis-specific configuration - built for RAM 3500, 4500, and 5500 commercial trucks rather than adapted from a Pickup package.
• EFI Live AutoCal V3 - proven OBD-connected tuning hardware for loading the supplied custom calibration and recording diagnostic data.
• Fixed C&C power options - choose stock-level power or a confirmed +60 HP calibration.
• Optional transmission tuning - select None, 68RFE, or AISIN according to the truck configuration.
• Two exhaust configurations - choose the standard DPF Delete Pipe or upgrade to a 5-inch Exhaust System.

The 2013-2018 Dodge 6.7 Cummins Cab & Chassis DEF delete kit combines the required tuning and mechanical components in one package so the exhaust, EGR hardware, and calibration are matched to the commercial chassis application.

Vehicle Compatibility

The RAM 6.7 Cummins Cab and Chassis DEF delete kit should not be ordered for a standard RAM 2500 or 3500 Pickup. Even when the engine and model year are the same, Pickup and C&C trucks can use different factory exhaust routing, aftertreatment placement, transmission configurations, and ECU strategies.

Fitment should therefore be confirmed from the actual truck configuration before the package is ordered.

Kit Components

• EFI Live AutoCal V3 Tuner - OBD-connected programmer used to store and flash the supplied custom tune. It can also be used for diagnostic data collection when technical support requires logs.
• Custom Engine Calibration - a vehicle-specific fixed tune prepared for the Cab & Chassis application. Available engine power is either stock-level output or +60 HP.
• DPF Delete Pipe - stainless exhaust pipe that replaces the factory DPF/CAT/SCR aftertreatment section while following the required C&C exhaust routing.
• Optional 5" Exhaust System - available instead of the standard Delete Pipe for customers who want a larger exhaust path and different sound profile.
• Muffler Option - choose Straight Pipe for a more direct exhaust note or With Muffler for reduced sound.
• EGR Valve & Cooler Delete Kit - includes the components needed to remove the factory EGR valve and cooler and close the associated engine and coolant connections.
• Optional 68RFE or AISIN TCM Tune - transmission calibration is selected according to the transmission installed in the truck. It is optional and must match the actual drivetrain.
• Installation Hardware - includes the clamps, block-off components, gaskets, and related parts supplied with the selected exhaust and EGR configuration.

CCV hardware is not listed as a standard component of this package and should not be assumed to be included.

Tuning & Performance

The 2013, 2014, 2015, 2016, 2017, 2018 6.7 Cummins Cab and Chassis DEF delete kit uses a fixed custom calibration rather than the multi-position SOTF setup commonly available on some Pickup applications.

The +60 HP calibration provides a moderate increase intended to preserve usable commercial-truck drivability rather than turning the C&C platform into a high-power Pickup tune. This distinction is important because the confirmed C&C tuning data does not support advertising the +30 / +60 / +90 / +120 / +150 HP Pickup-style range for this product.

EFI Live tuning changes the engine control strategies required for the removed DPF, DEF/SCR, and EGR components. Once the correct calibration is installed, the engine no longer requests regeneration for the deleted particulate filter.

Removing the restrictive aftertreatment section also allows freer exhaust flow. Throttle response, torque delivery, and overall performance may improve, while actual fuel efficiency, boost behavior, and long-term results depend on commercial body weight, axle ratio, load, engine condition, maintenance, and driving style.

Installation

Complete the EFI Live tuning before removing the factory emissions hardware. After receiving the AutoCal V3, provide the required vehicle information, including VIN, model year, transmission, transfer-case configuration, fuel-tank setup, and relevant engine modifications. The AutoCal serial number is also required before the correct custom tune can be prepared.

Once the tune is available, connect a stable battery charger, use the AutoCal V3 to flash the correct fixed calibration, and confirm successful programming. Only then remove the factory DPF/DEF/SCR section, install the selected Delete Pipe or 5-inch Exhaust System, and complete the EGR valve and cooler removal.

Standard metric hand tools, exhaust tools, penetrating oil, coolant-handling equipment, and safe heavy-duty vehicle support are normally required. Commercial bodies, auxiliary fuel tanks, previous exhaust modifications, and corrosion can make installation more difficult, so professional help may be appropriate on heavily upfitted trucks.

Ordering Information

Before ordering, confirm that the truck is a 2013-2018 RAM 3500, 4500, or 5500 Cab & Chassis with the 6.7L Cummins.

Select the required configuration:

TCM Tune

• None
• 68RFE
• AISIN

Exhaust Option

• DPF Delete Pipe
• 5" Exhaust System

Muffler Option

• Straight Pipe
• With Muffler

The EFI Live AutoCal V3 normally arrives before the custom file is created because its serial number is required for tune preparation. After receiving the device, the customer supplies the AutoCal serial number and requested truck information so the correct calibration can be generated.

Tune-file preparation typically requires several business days after the required information is received. The tuner, exhaust, and EGR components may also ship separately because the complete package contains parts from different product groups.

Vehicle-specific tuning and configured electronic products may have return restrictions once file preparation or programming has begun. Confirm the transmission, body configuration, model year, and selected exhaust before processing.

This package is intended for lawful off-road, racing, and competition applications.
