Are you sure the efi ecu has a vac connection, AND uses a map sensor as well, as I would not have thought so, it only needs one thing to know load so if it's in the ecu the map sensor it won't be outside as well seperately.

if you have a map sensor vacuum pipe coming out the ecu then it needs to go to the plenum
