Perfectly designed for GM L5P Duramax trucks, the Insight+ offers seamless integration and an intuitive, high-resolution 5 inch? touchscreen display.

With just a few swipes, you can track critical engine parameters in real time, adjust settings, and fine-tune your truck's performance to match your exact driving style, towing demands, or performance goals.

The Insight+ custom tuning capabilities mean you can load and manage tunes from your preferred custom tuner without additional hardware, keeping your setup clean and efficient.

Beyond tuning, the CTS3 platform offers a wealth of diagnostic tools, data logging, performance testing, and gauge customization, making it the most versatile monitoring and tuning solution on the market.
