jono Posted August 15, 2018 Share Posted August 15, 2018 If only a third of a century ago Australian RX turbo owners knew...the TPSwitch in Oz activates at 45° for "full contact" which I think bypassed O2 control The rest of the world got full contact at 30° throttle opening. Might be why imports went better if retained non Oz TPSwitch? Link to comment Share on other sites More sharing options...
