The Insight+ CTS4 pairs the Insight CTS4 gauge monitor with a license for custom tuning on supported trucks: the device backs up the factory file so a calibration shop can build custom files, which load back through the CTS4 — while the full Insight gauge display, DTC read/clear and data logging stay on board. The CTS4 display is a 5.5-inch full-color touchscreen — 21% larger viewing area than the CTS3 — running at 60 FPS with faster startup, physical buttons alongside the touchscreen, and the RCA camera jack back on board. Coverage: GM Duramax 2011–2023, Ford Power Stroke 1994–2021, Dodge/Ram Cummins 2007–2009.

Pre-order: Pre-orders are open now. Shipping starts November 3, 2026.
