Kennedy Custom ECM Programming for Duramax L5P
Currently working with the 2017-2019 models only. 2020-2023 coming soon. This is not quite as simple as the prior models as the ECM needs to be unlocked prior to loading the tune file and as a result, things may not move quickly.
With proper tuning it is NOT necessary to remove any parts. The DPF remains intact and still regenerates as needed. Looks, smells, and sounds stock. This saves a LOT of expense and the tuning can always be changed later if necessary.
