This is a stock timing map from an 06 6.0 full boost. Stock tune on truck. Why is the timing all over the place? Why wouldn't it be more linear and smoother? I even have a custom tune from a popular tuner that was put on by my sct years ago. The timing map is all over the place also. I am just trying to learn what's the thought behind this.
What would be a good starting point from idle up the rpm range? What would be a recommend advance maximum btdc? My truck has a stock motor, kc stage 3, 205/30 warrens. Daily driver/ commuter looking for maximum potential of my setup.
