Your best bet is to buy everything and then put it on at a time you feel comfortable with. Your fuel mileage with DPF present tuning will get worse most likely because of more regens. If you are gonna tune, might as well go all the way. Once you tune it whether its DPF present of removed the dealer can tell. SO, GO ALL OR NOT AT ALL is my opinion. I'm sure many would agree with my logic.
