    Fuel Delivery Help

    1st Problem, I bought injectors ( GP Sorensen # 800-1807n ) cant find the flow rate on them. Called GP Sorensen and they told me that they did not make these injectors for ten years, no help.
    2nd Problem, I was running out of VE table tuning so i increased the fuel pressure from 15 to 18.
    3rd Problem, Now on cold start open loop I am getting lean surge. Attached is a short log, bin, and ADX files.
