Chaos Custom Tuning MPVI4 Tune Files (2020-2023 Duramax L5P 6.6L)
The Chaos MPVI4 L5P Tune Files 2020–2023 are built for Duramax owners who want cleaner throttle control, stronger low-end torque, and consistent drivability from the 6.6L platform. These calibrations are designed for the HP Tuners MPVI4 interface and deliver a more refined driving feel compared to stock mapping.
Chaos Custom Tuning has a long track record of building files that work on both stock and lightly upgraded trucks. Whether your L5P is towing, daily driving, or running modest performance parts, these tune files improve throttle behavior, stabilize fueling, and provide smoother response under load.
Tune Options for Chaos MPVI4 L5P (2020–2023)
Chaos typically offers multiple performance levels (Level 1–5) to match towing, daily driving, or more aggressive use.
Each level is developed specifically for the updated 2020+ GM calibration strategies.
(If you want the specific HP levels listed, tell me and I’ll insert them.)
