K&N 17-18 Chevrolet 2500/3500 6.6L V8 Diesel Boost Control Module

The Boost Control Module instructs the vehicle's ECU to increase the amount of pressure in the manifold to a higher level before releasing it through the wastegate, keeping more boost available for when you need it (up to an estimate 49 horsepower and 82 lb./ft. of torque). The module reads the MAP (manifold air pressure), preventing over-boost and ensuring that power is added safely. Everything you need to set up your Boost Control Module, including the control module, wiring harness, and complete instructions are included. Featuring easy plug & play installation, it can typically be installed and ready to use in 30 minutes or less!

Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
