2011-2012 6.7L Ford Powerstroke

The DPF or Diesel Particulate Filter is part of the factory exhaust system on the 6.7L Powerstroke. H&S 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 our DPF Disclaimer in order to continue with the Install Download process.

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 6.7L Powerstroke, there are usually 3 EGT Sensors, 1 NOX Sensor, 1 UREA Injector, and 1 Pressure Sensor.

On the 2011 – 2012 6.7L Powerstroke, there is a UREA system that can be unplugged or removed completely when running DPF REMOVED tuning. The UREA system may also be left plugged in with no ill effects.

If you are installing H&S DPF REMOVED tuning, you must unplug the EGR system on your 2011-2012 6.7L Powerstroke if not installing an EGR delete. Failing to do so may result in damage to your EGR parts.
Please follow these instructions carefully to unplug and disable the EGR system:

1. Unplug Orange EGR harness found on top of the EGR cooler assembly. The yellow lock tab must be slid out before the harness can be unplugged.
   
2. Unplug the EGR Butterfly Valve located near the radiator fan shroud.
   

Did you know that your H&S tuning device also has the capability of tuning your transmission? Our transmission tuning for the 6R140 automatic transmission is custom tailored to mate with H&S engine tuning. Some features include: boosted line pressures, modified full and part throttle lock/unlock strategies, adjusted full and part throttle shift points, adjusted full and part throttle shift firmness, and modified torque management tables. All changes are designed to keep more power directed to the road instead of wasted in heat and friction. On our test trucks, we have seen 0.2 to 0.3 second quicker 1/4 mile times JUST from the addition of H&S transmission tuning! An additional unlock fee may apply, see www.hsperformance.com for details.

The 6R140 automatic transmission on the 2011 – 2012 6.7L Powerstroke has what is called Adaptive Memory and is constantly learning and adapting to different horsepower levels, temperatures, driving habits, etc. If you selected to tune the transmission during the Install Download process, the Transmission Adaptive Memory is automatically reset when the download completes. We highly recommend performing a Transmission Relearn procedure after installing H&S transmission tuning to help the transmission perform correctly with the added horsepower. The 6R140 automatic transmission will eventually learn over time on its own, but the relearn procedure gives a good baseline for the adaptive learning and helps to speed up the learning process. To perform the relearn procedure, please follow these instructions:
When re-training the transmission, ALWAYS follow posted speed limits. Do NOT attempt runs in adverse weather conditions such as snow, ice, rain, wind, or any other conditions that may affect your vehicles traction or impair your visibility!

1. After H&S tuning is installed, perform each of the following 0-80 MPH runs while in the HOT power level. During this relearn process, you may experience hesitation during shifts, hard shifts, or defuel patterns, all of which are normal:

• 0-80 MPH @ 25% throttle position, then slow down and come to a complete stop.
• 0-80 MPH @ 50% throttle position, then slow down and come to a complete stop.
• 0-80 MPH @ 100% throttle position, then slow down and come to a complete stop.

The Transmission Relearn procedure is complete.
