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! This device functions exactly like our Insight CTS3 monitor, but includes a custom tune license. This license allows Insight+ to read your trucks ECM/TCM and generate a factory back-up file to 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. 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 expandabilty and versatility like nothing else on the market. *Device does not include tuning. Custom Tuning calibrations must be purchased seperatley from your preferred Custom Calibration Shop
