Sydneykid, The MAP sensor on the wolf is in-built, so all you have to do is run a vaccum line from the plenum to the ECU, even people like me can do that. It is entirely plug'n'play, in the fact that it will work with the standard AFM (or aftermarket) but it does have the bebefit of being able to run MAP if you prefer. It comes with a 2bar map sensor, which can be upgraded to a 3bar MAP sensor if the need arises.
