Mini Maxx - Powerstroke - EGR Codes

When installing the H&S Mini Maxx on a 08-10 Ford Powerstroke 6.4L you may get a couple DTC's related to the EGR system. Be sure to unplug all the wiring going to the EGR system. Also check to see if "Easy Tuning" is selected. Go into the menu < settings < tune status. 

If "Easy Tuning" is displayed; uninstall the tuning and reinstall. Choose another option. This will eliminate any EGR diagnostic trouble codes that are set.
