---tab FAQ---

FAQ

Q1: Will this kit fit my 2019–2021 Ram 2500 or 3500?

A1: This kit is intended for 2019–2021 Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins. It does not fit Ram Cab & Chassis models. Because PCM and exhaust configurations can vary, confirm your model year, pickup configuration, engine, PCM part number, and selected exhaust option before ordering.

Q2: How do I know whether my PCM is compatible with the Mini Maxx V2?

A2: Check the PCM part number before placing your order. For this package, the supported PCM part number should begin with a number. A PCM number beginning with a letter may not be supported. If you are unsure, send us a clear photo of the PCM label or the complete part number before purchasing so that compatibility can be checked.

Q3: Does my truck require a Security Gateway bypass cable?

A3: A Security Gateway or OBD bypass connection may be required to allow the tuner to communicate correctly with a 2018-and-newer Ram. The required connection must be installed in the correct location before programming. Check the package contents for your selected tuner option and confirm that the required bypass cable or adapter is included before beginning the installation.

Q4: What is included in the 6.7 Cummins Delete Bundle?

A4: The package combines a Mini Maxx V2 tuner, an EGR delete kit, and the DPF exhaust option selected on the product page. Exhaust diameter, muffler configuration, finish, and other components depend on the options chosen at checkout. Review the selected configuration and packing list before disassembling the truck. Normal shop tools, penetrating oil, fluids, replacement fasteners, or other installation consumables may not be included.

Q5: What should I do before removing any factory components on my 2020 Ram 2500 6.7 Cummins?

A5: Read the current tuner and mechanical installation instructions first. Update the tuner with the latest compatible files, maintain stable battery voltage, verify that the tuner communicates with the truck, and save any required stock information before removing emissions hardware. Do not start mechanical disassembly until the required programming steps and package contents have been confirmed.

Q6: Can I install this full 6.7 Cummins kit myself?

A6: Installation may be suitable for an experienced DIY owner who is comfortable with diesel exhaust work, coolant connections, electrical connectors, and ECM programming. Rusted exhaust hardware, limited access to the Security Gateway, pipe alignment, or an interrupted programming process can add significant time. Professional installation is recommended if you do not have the proper tools, a battery maintainer, or experience diagnosing fault codes.

Q7: Which exhaust option should I choose? 4 inch or 5 inch?

A7: A 4-inch exhaust system is a common choice for owners who want improved flow without making sound the only priority. Adding a muffler generally helps reduce cabin drone during highway driving and towing. A straight-pipe or 5-inch configuration will usually produce a louder, deeper exhaust note and may create more in-cab resonance. Actual sound varies with cab, bed length, load, and the rest of the exhaust system.

Q8: How much horsepower or fuel-economy improvement should I expect?

A8: Results depend on the tune, truck condition, transmission, tire size, elevation, load, and driving habits. Owners may notice changes in throttle response, turbo response, and low-end torque, but a specific horsepower gain, exhaust-temperature reduction, or MPG increase is not guaranteed for every truck. Use a conservative calibration for towing and continue to observe the truck’s factory tow ratings and operating limits.

Q9: Will the kit extend engine life or require maintenance?

A9: No aftermarket modification can guarantee longer engine life. Reliability depends on calibration quality, installation quality, maintenance, operating temperature, and how the truck is used. Added torque can also place more load on the transmission and driveline. After installation, periodically inspect exhaust clamps, coolant connections, block-off plates, wiring, and hoses, and investigate any leaks or diagnostic codes promptly. Modifications may also affect the vehicle’s factory or extended warranty.

Q10: Is this kit legal, and can the truck be returned to stock later?

A10: Removing, bypassing, or disabling emissions-control equipment on an EPA-certified motor vehicle may violate the U.S. Clean Air Act and may also violate state or local inspection, registration, insurance, or vehicle-use requirements. An “off-road use only” label does not by itself make installation legal. Check all applicable requirements before purchasing or installing the kit. Returning the truck to stock normally requires reinstalling the original DPF, SCR/DEF, EGR components, sensors, wiring, and a compatible factory calibration. Keep all original parts and confirm the tuner’s recovery and return-to-stock procedure before installation.

Q11: Is this kit legal for road use?

A11: No, this kit is intended for off-road use only. It helps maximize performance for activities like trail driving, racing, or heavy-duty towing, but it may not comply with emissions regulations for public roads in some areas. Always check your local laws before installation.
