The actual term is "con chota sin chota" and Cesar says it in the "High Stakes, Low Rider" mission.
It translates to "with or without the cops".
The context is:
It's hard cash or your pink slip in the pot. Con Safos, eh. Then you pull up and race. First past the post wins, con chota, sin chota.
It probably means that the one who passes the post first, wins, even if he is chased by the cops.
