So whats the centrifugal doing? How much power timing, and when does it start, and how quick is it coming in, and at what rpm is it done by?
-And how much timing is in the can and at what vacuum does it start, and how much vacuum does it take to bring it all in?
-Its all well and good to say it has 9.5* at idle, but if thats all it ever gets its gonna be a lazy dog or a pig or both. we need the rest of the story.
-At about what RPM does it stumble when climbing that hill you talked about in post#7?
-What gear ratio are you running?
-Is you kick-down mechanism working and set about right?

From here, Id guess you have two problems;A) faulty pump or pump action, and B) faulty secondary tip-in. This is assuming the timings are all correctly operating and dialed in.Other fellas have touched on the pump issue.
