Magnetic or Dual Sync Distributor?

[Sewngo]

Anyone have any success running a magnetic pickup Distributor on a Borla Eight Stack system with a Holley HP EFI????
It came with the package from Borla but I think I need a Dual Sync Holley to better control the timing....
Advise please.
This is on a 460ci. Windsor Ford Racing Crate engine.

I see you've also posted a more complete version of this on the Holley HP EFI forum.

Excerpt from Holley EFI manual:
NOTE - It is not advised to use a magnetic pickup distributor to directly feed the magnetic trigger input of the ECU. If the magnetic pickup distributor is connected to the ECU via the inductive pickup trigger wires, the pickup/rotor/cap phasing must be corrected. This operation may require a phaseable cap or rotor or possibly machining to the distributor and is therefore beyond the scope of most users. Even with the phasing corrected, the electrical noise inside the cap (due to the high voltage cap & rotor terminals) may be strong enough to cause electrical noise interference. It is advised to use a crank trigger system or a computer-controlled distributor.
