      Thats what i thought.

      So my next question, is there anyway to adjust the mixture? My old mazda had a screw on the airflow meter that you could adjust for the mixture, (looked like someone had cut a groove into it) this one as you probably know, has just a round dimple thing on the meter.

        I'm not a bf expert but if it has a vaf like the bg chassis it can be adjusted pretty easily. Theres a how to I think in the engine management section.

          Cheers for that, there is a thread in there where someone has installed the exact same kit as mine. And a quick google search of VAF meter led me to this video.
