I came across a map you shared for a similar set up. You seemed to be the man when I comes to tuning based on comments I read. I loaded your tune into my pcv and before starting it I looked through the fuel and ignition maps looks good to me but the ignition map is pretty radical. As much as +9° adv. In some places? Is this correct? Any schooling you're willing to do would be much appreciated. I live at sea level if that matters. Thank you for sharing your knowledge.
