EGR Emissions Equipment

Unlike the previous years, it is no longer mandatory to unplug the EGR system when

installing H&S High Sulfur tuning. You may still unplug the EGR system if desired, or the

EGR system may be left plugged in without any ill eects. The entire EGR system can also be

completely removed with an H&S EGR Delete Kit when running H&S High Sulfur tuning.

4 - More Aggressive

NOTE: The injection timing adjustment will aect ALL power levels. This option can only be adjusted during the
