Sounds like a vacuum leak of the major kind.

Give us some more info, such as engine size, cam type, compression, intake type,etc. and we'll try to give you some ideas.
For what it's worth, 3-circuit dominators are a pain to try to work with on the street. Their street manners are poor, at best. With some work, they can be made somewhat acceptable. A 2-circuit dominator would be a better choice for a street-driven application, in my humble opinion.
