it says the Field sfc can go plus or minus 30% fuel delivery. my question is after i dyno my car how much of an affect are the Field % points going to have on the air fuel ratio? If i am running 13.5:1 air fuel and i wanna go down to 12.5:1, how do i know roughyl how many % points to increas the Field unit? Should i start with say 5% increase and go up form there?/
thanks guys
