A resounding YES! Removing the DPF is the best thing you can do to improve fuel mileage. Whether it's for your Cummins, Duramax or Powerstroke. Performing a DPF delete on you diesel pickup truck will result in a substantial increase in MPG. When your truck was new, fuel mileage was most likely in the range of 18-19mpg. As the DPF gets plugged fuel mileage slowly decreases. Most of our customers seem to get in touch with use when there mileage is around 13-14mpg or worse! After installing a DPF delete your fuel mileage will instantly increase.
