I use an MSD 8970 3 stage retard that uses the plug in chips/modules/pills for each stage of retard.
Have any of you ever had problems w/ these chips not pulling the amount of timing out that they are supposed to? I just wired stage 1 and 2 to work together so I can mix and match 2 chips to get the amount of retard I need.
I've been trying hard to NOT go to a digital programmable box, but this is making me think real hard about making the swap now.

Seems like the 13 and 14 degree chips still only pulled 12 degrees out.
