The HEI has a mechanical curve that I don't need. I want a locked plate. I don't need the vacuum advance, either. But, this dual pickup system might give me the capability to run more advance that the 18 degrees I need (once boost goes above 15 pounds,) by running the MSD 6-AL digital system off the "advanced" pickup until I get the turbo spooled and the boost goes over 15 pounds.
That would HOPEFULLY give me a quicker spool-up (with the additional spark advance) until I switch over to the "retarded" pickup, once the boost goes over 15 pounds.
