I am trying to tune my afc and evc, The evc either overboosts or maxes out at .5 bar, I am trying to run 1 bar... I have followed the directions to the tee, checked all the vacuum lines, and everything is right!!! the max i have been able to get out of either (a or b) setting is .64, unless I leave it wide open to set peak hold.. Please help if you can thanks
