I don't have experience with Dyna.But I use Boyer.They recommend timing by strobe at 4500rpm.at full advance Sent from my SM-G361F using Tapatalk
Not sure about your description, do you mean that both advance marks on the advancer were to the left of the static mark(extra advance) or to the right of the static mark(insufficient advance).
In that case you need to set the timing when running at full advance between the marks as you are running with too much advance for standard engine and will cause damage
They really are a piece of cake to install, here is the link to their instructions.http://www.dynaonline.com/skins/downloads/instruct/DS1-1_1-2.pdf
