Thanks! I have not paid that much attention to EFI retrofits, but I don't recall hearing of a problem with TBI on a dual-plane. The video doesn't really describe what they did to understand the problem. Clearly a carb has an advantage over TBI of using staggered jetting to compensate for manifold weirdness, but the video states the carb was square jetted. It's a shame they were not able to get to the bottom of this during the dyno time. Would another vendor's TBI had the same issue? I bet there is more to this....
