Sorry, this site changed it. 'Automatic Start Stop', or A S S, which is what it is.I don't know what the three asterisk mean but I'm going to take an educated guess and go with EGR.
If so, then the engines probably do come with it. Majority of all engines in the USA have an EGR.
You can delete anything you want, as long as you're willing to pay. These engines are new to the market, so the aftermarket hasn't begun doing much R&D to them.
