DPF Selection

The DPF or Diesel Particulate Filter is part of the factory exhaust system on the newer diesels. Mini Maxx offers tuning that allows the DPF to be left in place, or removed completely. If you are planning on leaving the exhaust system stock with the DPF in place, you will select PRESENT. If you have already removed the DPF or if you plan on removing the DPF immediately after installing your H&S tuning device, you will select REMOVED. If you select REMOVED, you must Accept the DPF Disclaimer in order to continue with the Install Download process.

DPF / Exhaust Sensors

When running DPF PRESENT tuning, it is required that all sensors located in the exhaust system stay in place and plugged in, otherwise you may experience a Check Engine Light (CEL) and even a loss of power (limp mode).When running DPF REMOVED tuning, it is recommended that all sensors located in the factory exhaust system be unplugged from the electrical harnesses. These sensors can also be removed completely with the factory exhaust if desired. On the 2007.5 – 2009 6.7L Cummins, there are usually 3 EGT Sensors, 2 O2 Sensors, and 1 Pressure Sensor.

EGR / Delete

If you are installing DPF REMOVED tuning, you must install a EGR delete kit. Failing to do so may result in erratic engine operation and loss of power.

Speed Limiter

This option allows for the adjustment of the factory speed limiter. Most 6.7L Cummins trucks have a 106 MPH speed limiter from the factory. The limiter can be adjusted from 55 MPH to 200 MPH. This option can only be adjusted during the Install Download process.

Tire Size Calibration

This option allows for the re-calibration of the factory speedometer to adjust for non-stock sized tires. For the most accurate speedometer reading when using non-stock sized tires, it is best to measure the diameter of the tire using a tape measure rather than going by the printed tire size. In additon, using a GPS is a great way to dial in your factory speedometer. Entering a larger tire size will cause the factory speedometer to read higher while entering a smaller tire size will cause the factory speedometer to read lower. The tire size can be adjusted from 25.5” to 45”. This option only takes a few seconds to change and can be adjusted at any time from the Tire Pressure Calibration menu.
