For those of you with the DPF Delete, what kind of mileage are you getting, how many miles are on your truck, what is the latest update you have, and what other mods are on your truck. I bought my truck new in October and started out around 10mpg. At around 12000 miles the mileage really started to climb to a consistent 18 on the highway and around 14-15 in town. I am starting to doubt the necessity of the DPF delete given the drawbacks. My truck is mostly stock for performance except for the superchip flashpaq. I have had no updates since I bought the truck, but was told i need the AX and G-30. Sooo, will it help enough to justify the loss of warranty? I am really starting to like my truck having had buyers remorse coming from a ford lariat.
