firin Supra Posted February 2, 2014 Share Posted February 2, 2014 Im full bpu just woundering as the pump is only on 9v instead of 12v at 4k rpm so isnt that goint make it run lean if im running higher boost before the transition? Quote Link to comment Share on other sites More sharing options...
mellonman Posted February 2, 2014 Share Posted February 2, 2014 The pump goes to 12v as soon as you go into positive boost so you will be fine, as long as you have the upgraded pump that is Quote Link to comment Share on other sites More sharing options...
