07.5 + 6.7L Cummins

The 6.7L Cummins is the latest of the B-Series engines, introduced mid model year in 2007. With an introductory rating of 350 HP & 650 lb-ft, it is also the most powerful B-series ever offered. The 5.9L ISB was replaced by the 6.7L to meet strict new diesel emmision requirements. To meet such requirements, the 6.7L is equipped with an EGR (exhaust gas recirculation) system, a variable geometry turbocharger (VGT), and a diesel particulate matter by more than 90 percent. A new, higher-pressure version of the Bosch direct injection system is used. For the 2013 model year, the Cummins was made available in three variations, the most powerful of which is rated at 385 HP and 850 lb-ft of torque.

DPF Delete (Cummins)

A Diesel Particulate Filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with functioning filter will emit no visible smoke from its exhaust pipe.

The DPF can hinder performance, mileage and reliability. The DPF filter installed on the latest generation of diesels reduces power by reducing exhaust flow, reduces fuel economy by using diesel to burn accumulated particulate and reduces engine life by allowing uncombusted fuel to seep into and dilute engine oil. Deleting the DPF system has become an extremely popular modification.

Key Benefits:

  • Prevent oil dilution
  • Greatly improve engine longevity
  • Add over 100 horsepower and 200 lb/ft of torque
  • Fuel savings of 3-8 MPG depending on application
  • No longer need to add diesel exhaust fluid

Although these kits are extremely popular, they are considered off-road/race only and will void your original manufacturers warranty. Liability waiver must be signed in order to purchase any DPF Delete products.

EGR Valve/Cooler Delete Kit (07 Cummins)

In a diesel, the primary function of the EGR system is to lower the amount of nitrous oxides (NOx) produced by the combustion of the diesel fuel. A portion of the engines exhaust gas is recirculated into the enine and combusted again. The problems with the EGR system arrise when the particulate being reintroduced into the engine, begins to clog the intake and EGR valve. Deleting the EGR is a popular modification that will increase the engines reliability. Tuner required.

Key Benefits:

  • Eliminates soot build up and clogged EGR Valves
  • Coolant tempatures run cooler because they are not running thru EGR Cooler
  • Hot exhaust gasses are not being re-routed back into the motor

Although these kits are extremely popular, they are considered off-road/race only and will void your original manufacturers warranty. Liability waiver must be signed in order to purchase any EGR Delete products.
