Run VSE - HP Tuners Custom Tuning - 2017-2023 L5P Duramax

Increase power output from 0-200RWHP on your 2017-2023 L5P powered truck with the usage of Switch On The Fly (SOTF) 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 benefit from shift control and Allision transmission durability, TCM tuning is strongly advised - this is applicable to 2017-2019 Trucks only!

What the user will see as a result of our calibrations are:

•  Increased throttle responsiveness (reduced or eliminated dead pedal)
•  Nearly the same or similar to OEM diesel exhaust fluid consumption (DEF)
•  Reduced EGR flow into the engine during normal operation without affect on emissions 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 habits)
•  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

Standard power levels are:

Position 0: + 0HP ~ Stock power

Position 1: + 30HP Heavy Tow

Position 2: + 80HP Light Tow/Economy

Position 3: + 135HP Economy/Daily Driver

Position 4: + 160HP Street

Position 5: + 200HP Max Effort stock turbo/fuel system

Federal Emissions Standards and Compliance:

--> Please be advised that these calibrations have a part number under EPA enforcement - as such will function only on trucks with working emissions control systems on them. SCR (selective catalyst reduction) DPF (diesel particulate filter) all NOx monitors, soot monitors, DEF (diesel exhaust fuel) monitors, reductant heaters/pump, EGT sensors, EGR sensors and other applicable Tier 4 emissions monitoring equipment will be required to be online before calibrations are completed and after in order for all OBDII compliance tests to be completed satisfactory and in accordance with current emissions standards. If this product is purchased with the intent to use on a truck with no emission equipment in place - we will not refund the purchase.
