Product Description
EDGE PRODUCTS 22403 PULSAR MD – 2019–2023 SILVERADO MD 4500/5500/6500 L5D DURAMAX DIESEL
The EDGE PRODUCTS 22403 PULSAR MD is the ultimate plug-and-play performance module for the 2019–2023 Chevrolet Silverado MD 4500/5500/6500 equipped with the L5D 6.6L Duramax. Fleet managers, work truck operators, and vocational drivers rely on the MD-series trucks for durability, and Pulsar MD enhances that capability with optimized throttle response, improved drivability, and increased power—all while retaining emissions system functionality.
Unlike handheld tuners, the Pulsar MD installs directly onto the engine’s ECM housing using factory-style connectors. This means no cutting, splicing, or additional wiring. The module delivers multiple power levels that can be changed on the fly, making it perfect for towing, hauling, and heavy vocational use. The Pulsar MD also improves pedal sensitivity to eliminate sluggish response under load, all while keeping factory safeguards intact.
It is designed specifically for the L5D medium-duty Duramax platform and does not delete emissions equipment. This makes it an ideal, legal solution for fleets and businesses that need enhanced performance without compromising compliance.
