    Starting a new thread with a question from the last post of another.

    If you are planning on using the stock injectors, I had a set flowed and they came out at 25 lb/hr at 43.5 psi. Comes out to 28.9 lb/hr at 58 psi (4BAR) which is the pressure the marine regulator outputs with with the vaccuum reference unplugged. Plugged in pressure comes down to around 52psi.

    Hog are you sure that those injectors come in all Marine intakes. I picked up so much airflow through the MAF its retarded my timing to 22° at WOT but thats not the biggest issue. Even using your flow value I am running 10:1 air/fuel ratio at WOT and my long term fuel trims are around -15%. Either I was tuning around a massive vacuum leak before or now have larger injectors than your intake came with. Fuel pressure rises to 60 psi with the KOEO.
