Rev-N-ator ignition boxes?

i run my vaccum advance off of manifold vaccum, i have it set to add 10 degrees of timing at idle. I run 14 degrees initial timing plus another 10 degrees from vaccum advance for a total of 24 degrees of timing at an idle and my total timing is set at 32 degrees.

why shoot your self in the foot on MPG? with that set up you might as well just run all mechanical. the point of vac advance is for at high vacuum like cruise you get more timing ON TOP of your mechanical. so what you really want it 14* or so initial, 32 total after mechanical around 2500, THEN another 10 to 15* of vacuum adv. granted if your right on the edge with your DCR your vac adv total might be less
