Powergrid and crank trigger issue

Hi guys,

having issue with crank trigger not adjusting timing when moving it. Have phased mag and trigger etc. timing on mag only is 27° and switch to trigger it shows 22°. Have tried moving it up and down atleast 8° and still doesn’t change. But the power grid is working.
Setup is, 509 bbc, 14/71, 12lt pro mag with points box, powergrid and EM trigger.
Any help will be greatly appreciated. It’s doing my head in.
