3.0 engine upgrade

  1. Driveline, Engine & DME Tuning
    I installed a complete 3.0 engine in my 2.5 and am getting lean run check engine light. Increased fuel pressure from 3.5 to 4.0 bar with not much improvement. Does anybody know where I can get higher flow injectors as I don't really want to reprogram the DME ?
