LMM 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 6.6L LMM Duramax, there
are usually 2 EGT Sensors and 1 Pressure Sensor.

to unplug or block-off the EGR system on your 6.6L LMM Duramax
to disable it. The EGR system is already disabled in the tuning
and will not function under any conditions. If desired, the
entire EGR system can be unplugged, blocked-off, or completely
removed when running H&S DPF REMOVED tuning.
LML EGR Unplug / Delete
If you are installing H&S DPF REMOVED tuning, you must
unplug the EGR system on your 6.6L LML Duramax if not installing
a complete EGR delete. Failing to do so may result in erratic
engine operation and loss of power. More
