2016-2022 2.8L Duramax Emissions Off Power Package

All of our Power Packages include CCS Custom Tune Files that will be written for your truck and driving style. If you are unsure about the tunes you'd like, just give us some information about how you use the truck.

Note: In order to have the tune files written specifically for your truck, we will require you to send us a "stock file" which can be obtained by utilizing the EFI Live Autocal once you receive it. 

Please be sure to input your VIN and Modifications at the bottom of the page.
