    Speed density Idle tuning running rough

    Hello

    Im working on idle tuning my car.

    Its a 1968 Chevelle Twin Turbo 5.3ls 4l80E
    Drive by wire 4 bolt throttle body with X-link
    high rise intake
    Twin GT35s
    Sloppy stage 2 cam
    Pac Valve springs
    DECAPPED INJECTORS 69lb/h
    60psi return style fuel system
    Speed density
    3 bar map.

    AFR around 11-12

    Ive had multiple files in the car, this seems to be the best chance to getting the car to idle enough to start tuning, is there anything else im missing?

    Dallas Re-start Speed density rev 2.hpt
