LLY Duramax Dash Mounted Tuners

Add dyno-proven horsepower, improve towing capability, and monitor vital engine parameters in real time on your 2004.5–2005 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LLY Duramax dash-mounted tuners and digital touchscreen monitors. Combining the functionality of a multi-stage power programmer with a full-color, comprehensive digital gauge display, a dash-mounted tuner keeps critical powertrain health metrics directly in your line of sight. Instead of cluttering your cab with multiple analog pillar gauges, these intuitive color touchscreens allow you to track real-time parameters such as exhaust gas temperatures (EGTs), turbo boost, transmission fluid temperature, fuel rail pressure, and injector balance rates with user-configurable visual and audible safety alerts. Furthermore, they allow you to switch power levels, adjust throttle sensitivity, calibrate your speedometer for larger tires, and read or clear diagnostic trouble codes on the fly. We stock industry-leading dash-mounted tuning and monitoring displays from top brands like Edge Products (Insight & Evolution CTS3).
