    You need data on those injectors first. Where did you get them?

    Hey thanks for the reply guys here's my injector info 42lbs @43.5psi (300)kpa
    .. I know my fuel pressure is around 58psi an these are 42lb @ 43.5psi and I know I need to change
    -flow rate vs kpa
    -minimum pulse width
    -default pulse width
    -short pulse adjust/adder

    an I also have a 2 bar map sensor I picked up I hope this info can get me a starter tune as I don't want to mess this thanks guys.
