Before you consider the DPF delete, take it in to the dealer first for TSB 8-13-2. It's a PCM flash that tremendously helped our F-250. Just came out a few weeks ago. There's no highways around here, only city/hilly driving. We're now getting 15mpg hand calc thru 3 full tanks of fuel... before we were getting 11.6 since last year!
