Wow. That really sucks. That dip in the 6K range is definitely not good. I still think that the parts have the potential to make good power. Obviously the tuning is out of whack. But how much out of whack is the question.
At this point, everything is a guess. You need cold hard facts to decide on a gameplan. I really think you need to get a proper air/fuel reading with your dyno runs. There's too many variables and guessing what to fix with 2/3rds of the info will only cause more frustration and a lighter wallet.
