So I have a 2013 dd15. Just took it to a certified freightliner and they are saying it’s set at 455 and 1750 with no other options. But the truck has no balls at all. Does anyone have any insite on what my options are?
Call and see what these guy can do. They do remote tuning. They have dealers with laptops and they connect to Pittsburgh power in PA and they have custom tunes. It's all legal, I'm not sure what they can do on DD15.
