If you are still setting fresh codes for the map sensor, then that is the circuit that you "must" concentrate on.

Believe what the OBD system is telling you here.

There is more to the MAP sensor circuit than the sensor itself.

Just because you replaced the vacuum line doesn't mean that the vacuum source feeding it is good. You must verify good vacuum.

The connector and wiring are also still in play.

Check em all.........
