I understand completely what you are talking about. I have played with vac. advance but now that I have an engine with a smaller cam than my previous one, my vac can is too sensitive. I can't remember the part number of the can but it's the one that comes it with a very low vac signal. As soon as the engine is running vac advance is all in and when I'm at cruise I'm pulling about 20 inhg. I ditched the vac advance when I broke the lands on two pistons. I couldn't get rid of the pinging with it, and that's hooked up to manifold vac. Maybe I should get a stock can or an adjustable one.
