3-Port Electronic Boost Control Solenoid

The GrimmSpeed 3-Port Electronic Boost Control Solenoid is engineered to enhance boost control for Mitsubishi EVO 8 and 9 vehicles. This solenoid flows 10% more than competing units and is specifically designed to work with the factory EVO ECU, drawing the same power as the OEM solenoid but offering superior performance. Installation is simplified with a plug-and-play harness that connects directly to the OEM wiring, meaning no splicing or soldering is required. The unit features nickel-plated brass fittings, ensuring longevity and resistance to breakage, unlike plastic alternatives. It comes with a model-specific bracket for a direct bolt-in installation, providing a clean and factory-fit appearance. This electronic boost control solenoid offers advanced tuning capabilities. Unlike manual controllers, it allows for precise boost mapping across the RPM range, enabling tuners to optimize power delivery and prevent detonation. The product explicitly requires an engine tune for proper operation. Tuner feedback highlights its ability to make acute adjustments, provide better spool, and offer more granular control over boost curves, potentially reducing wastegate duty cycles by half. The GrimmSpeed 3-Port Electronic Boost Control Solenoid is compatible with Mitsubishi Lancer Evolution 8 and 9 models (03-06).
