Were did i say this truck is lifted merc? Sure dont look lifted? I said my old dodge had a 6 inch lift and was better on fuel then this ford and a stock ford tire is 34.6 and now the truck has 35s other then width tire was the same size by the stockers.
merc cAnt read? Anyone else see the logic in that? mr hot shot if you do a no power/low power tune and Drive the truck like a adult and your not a dink to your dealer they often look the other way
Sorry thought you had it lifted too. Just don't see the reasoning to delete to save 8-10% fuel economy. The numbers don't get you on the positive side for 5+ years. Those tires and rims are heavy and more roll resistance, they're likely costing you 5-8% alone.
The biggest concern is the warranty on a 80K + truck. If you say it will be fine, ok, I've never dealt with Ford but have had warranty denied with other brands because of mods. Your approach to save a few dollars in fuel seemed foolish, but if your warranty will remain and you're able to keep the truck past 5-6 years with 30k km ayear, you'd come out a head with fuel. I've deleted my truck after the def heater went and the repair was more than deleting, the fuel economy gains are very minimal.
