what i found worked best using a dizzy on a boostd applacation is to set the timming at 0* at idle with the vac unhooked, than connect the vac line to MANIFOLD vac.
iirc vac advance is 10* and mech advance is10*
this will give you 10* at idle/low rpm 20* under cruse and the boost pressure retards it to 10* when your under boost. i found this to work very well for power and fuel econemy, way better than the locked dizzy a lot of people use.

This is how I have it wired currently using the FC leading coil as wasted spark driven by a MSD 6A and a gutted ignitor and trailing going through the distributor.

I've been running this way since the install last November and haven't had an issue. If you mash the throttle under 3-5K it bogs a bit but I try not to drive like that anyway.
