Boost Retard Module for Power Grid

The Boost Retard Module for Power Grid by MSD IGNITION is a precision ignition timing control device engineered for high-performance engine builders and enthusiasts who demand dynamic spark advance management under boost conditions. This module is designed for carbureted and fuel-injected engines running forced induction systems, allowing tuners to safely retard ignition timing as boost pressure increases. If you're building a turbocharged or supercharged engine and need intelligent timing compensation to prevent detonation and maximize power output, this MSD component delivers the electronic sophistication required for reliable, repeatable performance.

The module works by monitoring boost pressure signals and automatically reducing ignition advance to maintain safe combustion margins as intake manifold pressure climbs. This prevents knock and detonation—the primary threat to forced-induction engine longevity—while allowing baseline timing to remain aggressive at cruise and light-load conditions. MSD's engineering ensures smooth, linear retard curves without stepping or hesitation; the compact design (6.05 x 2.2 x 7.85 inches) permits discreet installation in tight engine bays, and the lightweight construction (0.56 lbs) adds negligible weight penalty. Integration with MSD's Power Grid ignition systems provides seamless communication and factory-grade reliability.

This module is ideal for street and competition engines equipped with intercoolers, wastegates, and boost controllers seeking plug-and-play timing management without expensive engine computer reflashing. Installation pairs directly with MSD Power Grid systems, making it a straightforward addition to existing setups. Compatibility depends on your specific ignition platform, so verify your MSD controller model before purchase to ensure proper signal integration and harness matching.
