As for your cam, what are the specs? Your idle vacuum is 83kpa, which suggests a pretty large cam but your air flow (g/cylinder) peaks at 5200 and the falls away towards redline (I'm assuming your airflow model is correct here and the g/cyl are accurate), a good high horsepower NA package will hold close to the peak g/cyl all the way to 7000 or higher. You MAP pressure is not dropping to suggest an inlet restriction, it looks to me like you cam or heads or exhaust are not up to the task if its big power numbers you're chasing, if its mid range grunt your after you probably have the right cam but its just not going to give very high peak horsepower numbers. My stock bottom end LS3 with heads and cam makes 485rwhp with a 4500rpm converter unlocked, seems like there should be more in your combo since you have more cubes than me.
Additionally are you still running the stock fuel system, if so what's you injector duty cycle? Stock injector would be pretty close to maxed at that air flow.
