17-19 L5P Duramax RUNVSE ECM Tuning

Increase power output from 0-200RWHP on your 2017-2021 L5P powered truck with the usage of Switch On The Fly (SOFT) tuning using steering wheel controls or a manual control knob. The increased power outputs are seen with no hard part changes to the truck and require all emissions equipment to be fully intact and in good working condition. For users wanting the maximum benifit from shift control and Allision transmission durability, TCM tuning is strongly advised - this is applicable to 2017-2019 Trucks only!

•  Increased throttle responsiveness (reduced or eliminated deadpedal)
•  Nearly the same or similar to OEM diesel exhaust fluid consumption (DEF)
•  Reduced EGR flow into the engine during normal operation without affect on emmissions NOx output
•  Increased torque in all power levels which allow TCM to command the next higher gear (fuel savings)
•  Increased time between DPF regenerations
•  Increased fuel economy (average increase depends on driver habbits)
•  Quicker transient response times to degraded air/fuel conditions
•  Enhanced and more conservative engine backdowns from sustained high EGT conditions
•  Enhanced and more conservative timing control during high load conditions (towing)
•  Overall better drivability and end user experience
