I need help tuning this thing. I used jamesk map but it was running way to lean so i adjusted from 10.3@500rpm ... 9.2@6500rpm incrementing -0.1 through the rpm range. My afrs seem fine but im wondering what vacum ranges should i fill. I filled from -16h to 0 vacum pressure. Again what vacum ranges should i fill? My car idles with a vacum range of -19 or so. This thing is confusing.
