Do I Need To Modify Or Add Anything Else When Fitting A Bored Out Throttle Body?

Our throttle bodies to suit the V6 & V8 engines are a direct replacement for the factory item so no other modifications are required.  

We do however recommend that when fitting a bored-out throttle body on a MAF tuned Commodore (Ecotec & VS series III Holden V8) that the throttle body is fitted in conjunction with a reprogramed PCM/memcal as the throttle body will alter the transmission shift points somewhat.
