The Insight+ takes truck performance to the next level, combining state-of-the-art monitoring, just like our standard Insight CTS3, but with added tuning capabilities! Pre-loaded with a custom tune license, the Insight+ lets you read your trucks ECM/TCM and creates a back-up file that can be sent to your preferred and Edge approved 3rd Party Custom Calibration shop. That 3rd party tuner can create the custom files specific to your truck and email them back to you, at which point you can simply drag and drop them from your PC to the Insight+ folder, and return to the vehicle to finalize the flash process. This kit is built specific for 2017-2019 GM L5P Duramax applications and includes all required hardware to be able to monitor and unlock/flash ECM 3rd Party calibrations intot the truck. Kit includes our revolutionary Locksmith unlock tool, ECM unlock harness, and our cast A-pillar mount for an OEM like fit of the Insight+ monitor in the cab. Monitor your trucks vital parameters in real-time while enjoying the flexibility to load custom tunes tailored to your driving needs from your preferred tuner. Insight+ offers unmatched monitoring at your fingertips with expandibilty and versatility like nothing else on the market.
