I have a 2018 Colorado 2.8L. I see on other posts guys talking about how often there truck Regens. How do you know the truck is going through a regen? I have never seen any message that a Regen is happening. Is there some setting I have to change or ?? Thanks. By the way I love the truck 62,000 miles and a lot of them pulling a 5,000 lb toy hauler around Indiana and Michigan. I did the duramax tune and it runs great with great mileage pulling the trailer 16-18 MPG.
