Crafted with meticulous attention to detail by US-based automotive engineers, this AFM/DFM Disabler elevates your driving experience in several key-ways. Stop the engine shudder and hesitation often associated with cylinder deactivation (AFM/DFM) and rediscover a smooth, uninterrupted ride. This translates to a more enjoyable driving experience, especially for those who've grown accustomed to the disruptive feeling of cylinder deactivation. Unleash the potential of your engine: Engineered with high-reliability automotive-grade components designed to withstand extreme temperatures (-40°C to 85°C), this module ensures optimal driving in any environment. By preventing cylinder deactivation, you potentially reduce wear and tear on lifters, promoting long-term engine health. Additionally, for those who've invested in an aftermarket exhaust system, this disabler maintains a consistent and satisfying exhaust note, truly allowing you to showcase the full potential of your vehicle's sound. Peace of mind with ease of use: This disabler device prioritizes both user-friendliness and peace of mind. The compact design ensures a discreet placement under the dash, and the highly optimized algorithm guarantees swift deactivation once vehicle conditions allow. Furthermore, you can enjoy the flexibility of a user-selectable multi-colored LED that seamlessly integrates with your vehicle's interior lighting. The module also features a single, optimized-brightness LED for clear status indication and a smart diagnostic LED for troubleshooting purposes. Unparalleled quality and convenience: Rest assured, every single unit undergoes rigorous 100% functional testing and serialization for complete traceability. This commitment to quality ensures you receive a reliable and trustworthy product. Installation is a breeze, and the disabler doesn't alter your vehicle's computer, leaving no trace upon removal. The broad GM vehicle compatibility makes it suitable for most V6 & V8 AFM or DFM vehicles, including Chevy Silverado models (optimized for a seamless fit). This disabler also serves as a great replacement for the popular Range Technology RA003. Please note: This product is not compatible with GM 5.3L/6.2L engines with 10-speed transmissions utilizing AFM technology.
