How close are they synced now?  Are you removing linkage to do that? Are dog bones the exact same lenght?  

I’m using cable control on the linkage. So the issue with them is the cascading effect of using cable on one ITB that has direct linkage to the other two . It causes #1 ITB to open up sooner no matter how I try to adjust . I also have #4 port that doesn’t flow as much air as the rest . Maybe a butterfly issue - slightly off.

I would go with rod linkage but I’m pushing it for time to make it to ZCON . 
I’ve tried syncing the best I can at lower TPS by just holding throttle open with cable adjustment and calibrating 3-6 . 
Once I’m around 12+ TPS - AFRS blend much better .

As far as #4 - I  will address this with injection trim . It’s just light cruise where I have to pull some fuel . 
I’d love to try the rod linkage but I’ll have to see how much time I have . It won’t help with the center ITB . I’ll have to take it off and see about doing something with the throttle plate . Again -  it much time for that right now
