Show original supplier description
This controller provides comprehensive management of the factory bypass valve, allowing for seamless integration and optimal performance. The primary function of this controller is to replicate the authentic Hellcat driving experience. It ensures that the bypass valve reacts precisely to pedal input, which translates into exceptionally smooth throttle response and peak performance gains. This makes it an ideal component whether you are performing a direct Hellcat supercharger swap or installing an aftermarket supercharger that uses an OEM bypass valve. Designed for 5.7, 6.1, and 6.4 HEMI engines, the MMX Hellcat Supercharger Boost Controller is presented as an easy-to-install and cost-effective upgrade for HEMI engine swaps. It aims to imbue your vehicle with the distinctive performance characteristics and driving feel associated with the Hellcat model. **Important Installation Note:** For 2005 and 2006 Dodge Charger models, a direct splice of the throttle wire from the pedal to APPS (Accelerator Pedal Position Sensor) Signal 1 is required, as detailed in the provided "05-06-Charger-Pedal-Wire-Splice.ODF" document.
