So I did a delete on the def, went from 12.5 l/100km down to 10.2.
the dpf was removed and the def tank removed. I have had it since 30k km but once I did the delete at about 270k, it sure made a difference on the drivability and mileage.
Hi,
I have a 2015, deleted def, mild tune. Removed the stupid levelling kit that the previous owner put in. I use it for work so it always has something in the back and it sits nice with some weight in the back.
This truck is on its 3rd engine. All before I got it at 30k kms. Been ok since...
