Yes despite what some people might say, opening VBoost early only hurts power.......your dyno graph is one of the best examples of documented proof that I've seen.
It should be a sticky.......
You are a little bit rich on the main based on the AFR readings....a little smaller jet might get you a couple of HP.
Opening Vboost earlier, makes more grunt at part throttle openings, because it acts like you were opening buterflies faster. That is why so many peopole feels it s better.
But at WOT you loose HP, because of the velocity drop in the intake pipes.
6000 is the best setting, or custom Vboost opening with Ignitech (Open earlier at part throttle and 6K near full throttle)
