I had it mildly happen with a 11.5:1 2 liter set-up. Would only not catch some of the time.

Definitely a fixable problem. Pretty sure it was just a matter of advancing timing around the desired idle range on my particular set-up (2 liter, 13:1 ish compression, skunk stg 2 cams, TWM ITB’s, 7lb flywheel).
