I have a VY L67 motor and have noticed that Mace have the LS1 throttle body adapter plate for sale, If I bought the adapter for a LS1 throttle body does the mass airflow sensor need replacing or does the car need a mafless tune for it to work properly. If

While you could install a LS1 throttle body in conjunction with the standard V6 mass airflow meter, it wouldn't be worthwhile. Most importantly though, it would still require a custom tune even if you were to use in conjunction with the standard V6 mass airflow meter. A more cost effective induction upgrade solution to consider, given your current L67 bolt on mods, would be our larger throttle body and memcal to suit as shown in the links below.
