Right, i've been looking at my settings, on the vid posted, i had the extension set on 24 from full soft out of a possible 40 clicks. On the afco instructions, for heavy door cars slower than 9.90 at the faster end it says 6-8 clicks from full soft, i've moved it to 8 for next time out.
On the comp i had 14 clicks from full soft out of a possible 24.
Afco says for 12-16 from full soft, so i've moved them to 16.
So basically, the comp is around the same but i've loosened the ext 8 clicks.
