Map= manifold absolute pressure sensor. Guess the zr1 map helps with tuning. There was a debate about wether it is NEEDED but with it u can read boost througb your odb2 port. The zr1 plugs are just 1 step colder then stock which again not absolutely sure they r NEEDED. I think the sensor is about $40 and plugs $60-80.
