FiTechs only solution is to use manifold vacuum, sounded like a known problem. With my initial set to 15, won't this cause hard starts?
if you set the initial to 15 on manifold when running I could see that it automatically being way retarded from that when starting (from no vac adv) could cause very hard starting. Maybe there is enough cranking vacuum to activate it, I never thought about that. You might Google it or call FiTech or Don at FBO (he is a manifold afficionado) As they've for sure dealt with this. holler how it goes.
