There are two Manifold Air Pressure (MAP) sensors. One is located on the front of the inlet manifold, on the right hand side as you stand in front of the engine, this measures pressure after the supercharger. The other is located just above the thermostat housing, it has a pipe connected to it which plugs into the plastic inlet to the supercharger, this measures pressure before the supercharger.
The first one will be easy to remove, you may have to remove the intercooler for access. The second one is trickier, I've not removed one of these before, but you may need to unplug the pipe from the plastic intake pipe - which means moving the front end module forward, alternatively you may be able to remove it from it's bracket and remove the pipe at the sensor, I'm not sure which. Perhaps someone else can fill in the gap here?
