Who on the list is successfully using a

Boost Retard Mechanism from MSD, or a 12AT Distributor?



I've heard the 12AT distributor will only retard a total of like 6 degrees, so it may not be enough when running 17psi+



I already own a few MSD6AL's & MSD Blaster II coils and don't want to change them unnecessarily.



I am not sure if I can add a Boost Retard

to them (MSD6AL's) so I could retard BOTH Leading and Trailing simultaneously.



I am asking, because I figure it's better than just using a locked distributor for off boost driveability, which seems to be what Iwill be using with my Holley 650 for a while, until I get my Haltechback from Australia.



Any ideas?
