Tuning is pre-loaded ready to go. No additional purchase or download is required. The H&S Mini Maxx includes DPF present and DPF removed tuning.

Eliminate the following components (if equipped) without setting any diagnostic trouble codes or check engine light:

  • Diesel Particulate Filter (DPF)
  • Catalytic Converter (CAT)
  • Diesel Oxidation Catalyst (DOC)
  • Selective Catalytic Reduction (SCR)
  • Diesel Exhaust Fluid (DEF)
  • Exhaust Gas Recirculation(EGR)

Fuel Mileage –Expect to see significant fuel mileage gains. If your DPF is plugged up your probably averaging 13-14 mpg. More or less depending on the severity of the restriction. After installing theH&S Mini Maxx and deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg. Larger tires and poor driving habits will reduce mileage.

*2015/2016 Ford – Some trucks may set a crank case ventilation sensor code. This will set a check engine light. The truck will run properly but you will still have a check engine light and DTC.
