How much is the deletes and the chips helping with mpg? I have an 08 with the 6.7 that gets at best 13.2 and want something done about it.
I was gettin 13 bone stock, had the egr and dpf filter deletes as well as a new tb exhaust and the h&s xrt pro. Now im at close to 19mpg's and ive installed a 6" lift and 37x12.5 tires and the truck is stupid fast.
