Unlike most files on the market, CCS is true custom tuning for your Duramax. Just let us know what you're doing with the truck and we will get you tuning that is written specifically for your truck and your usage.
Coopers Custom Solutions writes their custom tunes for the Duramax in Canada and is highly regarded as one of the best custom tuners for the Duramax engine. Allow you to make safe and reliable power in your LML.

Tuning
Single Tune
A single tune option is perfect for customers who are just looking for a mild tow or economy tune and do not foresee the need to switch tunes. The truck will always run it much like the stock tune, perfect for customers who are not the only ones driving their trucks. We can set up a single tune to any power level or configuration.
5 Tunes
The 5 Tune option is great for customers who want the ability to turn up and down the power of a tune as a result of the changing circumstances in which you plan to use the truck. For example, if the truck is empty you can turn up the power to have a little fun, then turn it down when hooking up to your holiday trailer to minimize stress on the drivetrain.
