Title:

2015 Cummins ISX 2250 Fuel Economy

Text:

Did a delete on my 2015 International Lonestar with a Cummins ISX 2250 500hp. My mpg dropped from 6.0 to 5.4. It also has an automatic 13 speed transmission. Why the drop? I thought deleting an engine increases the fuel mileage. The truck runs a lot better after the delete but fuel mileage went down.
