Just like the Cruze Diesel, we expect the Colorado and Canyon to be using a different controller and engine to the rest of the world. What that holds in terms of tuning is UNKNOWN until we get our hands on a controller.
FWIW, the 2.5L and 2.8L are currently sold in many parts of the world without a DPF.
