TE, you're right. All the way down to servo arm and throttle lever angles. Everything has to be set properly to get up and down synchronization, that's one of the many reasons I like to use the electronic synchronizers. There is always the slight difference from one engine to the next, set everything as exactly as you can, the engine computer does the rest.
