Default Re: My first plenum pull!

Looking at the pics, it seems your 2ndary actuators are installed 180 degrees rotated - a common factory mishap.
Some claim, 2ndary will come on stronger if this condition is corrected. However, I have seen posts that after being installed rotated for a long time, actuators will not function correct if rotated into correct position. If I were you, I would rotate them into correct orientation, apply vacuum w/ hand held pump and see if it allows 2ndary to open w/ less amount of vacuum and also if correct position will open the 2ndary flap wider.
I know, some will chime in and say just disconnect the system...
