set ke-jetronic (g-kat)?

first of all a friendly hello to the community. I’m new here and I have a question about the ke-jet. and that, can someone please explain to me how I best put the mixture in the full load range. have converted an escort with l4b motor to turbo. now I like to adjust everything still properly before you step on the gas. not that the mixture becomes too lean and the pistons give up the spirit. so the screw on the quantity divider is more for the co content/empty run mixed. but how do I get the sprite quantity up at full load? doesn’t want to turn around now, before then garnix is more true. the whole is monitored by a wideband lambda with display. would be happy about a few tips.
