That sounds like a lot of discrepancy for carb balance to resolve, IMHO. I would recommend balancing the carbs, first. Next, I would do a compression check (both wet and dry) for both cylinders and compare them.

Also, how did the dyno tech determine the difference in the two sides? With a crossover pipe in the header, it is difficult to use a sniffer in the end of the silencer and determine which side is which. Did he use the header holes before the crossover for his EGA probes? More than a few have reported that one side silencer is hotter than the other side and this is probably a result of the crossover being where it is--a bad location--too far from the exhaust port, IMHO.
