Compact Guitar Tuner by Big Boss

Description

If you’re looking for advanced diagnostics and monitoring without engine tuning, the PDI BIG BOSS® Tuner Lite gives you powerful tools to monitor and manage your truck’s systems without modifying the ECM.

The Big Boss Tuner Lite plugs directly into your truck’s diagnostic port, allowing you to quickly access custom gauges, vehicle settings, and diagnostic features. With simple on-screen instructions, you can monitor engine data, run system tests, and troubleshoot issues right from the handheld device.

Unlike performance tuners, the Tuner Lite does not modify or flash the ECM, making it the perfect option for drivers or fleet operators who want diagnostic control and monitoring without increasing horsepower or torque.
