Lean/Rich compromise

My 3.0 '77 has an unusual mixture problem that I can't seem to over come. If I adjust the idle to proper mixture, the mid-range acceleration goes way lean until boost, then it absolutely flys!. If I adjust the idle to too rich, the acceleration is good but the boost power is soggy, as if too rich. That being said, it appears my CIS is delivering a range that can not be adjusted to achieve all the correct mixture delivery. It's as if ther eis a dip in delivery that can't be overcome. Any suggestions?
