The EDGE PRODUCTS 17-19 GM P/U 6.6L Pulsar Tuning Module with CTS3 is a performance engine control unit designed for 2017–2019 Chevrolet and GMC pickup trucks equipped with the 6.6L Duramax diesel engine. This programmable module allows users to adjust engine parameters and fuel mapping, enabling optimized horsepower and torque delivery across different operating conditions while maintaining compatibility with the OEM CTS3 (Custom Tuning Software 3) platform.

The Pulsar module integrates with your truck's factory instrumentation cluster via the CTS3 interface, providing real-time data logging and on-the-fly parameter adjustment without requiring external tuning equipment. This design preserves OEM diagnostics compatibility while enabling custom performance curves tailored to towing, daily driving, or off-road duty. The module's configuration supports multiple tune profiles, allowing operators to switch between power and efficiency settings based on load and conditions. Dimensions of 10.5 x 6.8 x 17.6 inches and a weight of 5.35 lbs ensure the module fits standard installation locations on modern Duramax platforms.

This tuning solution targets diesel truck owners prioritizing engine response without full-system modifications. Whether managing heavy towing loads, improving throttle response on daily commutes, or optimizing fuel economy during consistent highway mileage, the CTS3-compatible Pulsar module delivers programmable control that adapts to varied duty cycles. The 2017–2019 model-year specification ensures precise compatibility with Duramax generation 5 emissions and fuel injection architecture, critical for maintaining system integrity across warranty periods and emissions compliance in regulated markets.
