I tuned and deleted my 2018 to the muffler and I was averaging 26mpg. Now a couple of weeks ago I deleted my muffler but now it seems like I lost fuel mileage. Now has anyone else noticed that? Or will it take some time for the ECM to "relearn" and gain that back? Or does the Ecodiesel need some constant back pressure to be more efficient?
