I am having difficulty balancing the TBs, where I cannot get them synchronized at both idle (1100) and 2-3k RPM. I can balance them with closed air bypass screws at 2.5k, but as soon as I ease off the throttle one side sucks a lot more air, and opening bypass screws does not help. On the other hand, I can balance the TBs at idle with open bypass screws, but then the balance goes way off opening the throttle ... what gives? Any ideas? I set the valves to world spec, rubber intake boots are good, I do have pods and they are the same. A.
