The Edge EZ with Insight CTS4 Kit for 2024–2026 Chevy Silverado HD and GMC Sierra HD 6.6L L5P Duramax combines simple plug-and-play diesel performance with Edge's next-generation digital monitoring. Designed for Duramax owners who want more power, better throttle response, and added towing confidence without flashing the factory ECM, the EZ delivers gains of up to 63 horsepower and 140 lb-ft of torque while the Insight CTS4 keeps critical vehicle data right at your fingertips.

Choose from five power levels adjustable on the fly through the Edge EZ smartphone app, ranging from +20 HP/+60 LB-FT at Level 1 to +63 HP/+140 LB-FT at Level 5. A built-in Throttle Booster gives you seven adjustable pedal sensitivity settings within each power level, allowing you to fine-tune throttle response for daily driving, towing, or maximum available performance. Cold Engine Protection keeps the truck at factory power levels until the engine reaches operating temperature.

Installation is completely plug-and-play, using factory-style connections with no cutting, splicing, or ECM flash tuning required. Because the EZ doesn't reprogram the factory ECM, it's also dealer and warranty friendly. Simply remove the module to return your L5P Duramax to its factory configuration without leaving a tuning footprint in the ECM. Edge testing showed the added performance can shave up to 0.31 seconds from 0–60 MPH acceleration and add 3 MPH in quarter-mile testing.

Use the Insight CTS4 to monitor supported L5P Duramax engine, drivetrain, temperature, pressure, emissions system, and other critical vehicle parameters through customizable digital gauges. Set alerts and warnings, log vehicle data, read and clear supported diagnostic trouble codes, and expand your monitoring capabilities with compatible EAS sensors and accessories.

Whether you're towing a heavy trailer, hauling equipment, or looking for a stronger and more responsive daily driver, the Edge EZ with Insight CTS4 Kit for 2024–2026 L5P Duramax delivers easy-to-use power, adjustable throttle response, and advanced vehicle monitoring without traditional flash tuning. Plus, the EZ is 50-state compliant under CARB EO D-115-30, delivering emissions-friendly performance you can use with confidence.

Plug it in. Power it up. Monitor everything. Take Control with EZ and Insight CTS4.
