I cant see the graph, but will look later.
When you see torque peak hard then fall but power stay the same the turbo is out of breath (too far right on its compressor map). A bigger turbo would simply shift the torque curve to the right. More torque at higher rpm is more power.
When you increase boost and dont see any more power, the turbine is choked.

That's a healthy cam for a 4.8!

Get a bigger turbo on that thing, and let it eat.

Maybe mine will be together in the spring, and we could meet up somewhere. There is usually a spring dyno day at Brians, or maybe at a track somewhere. I didn't really get to talk to you last time we were at the dyno day at the same time. There aren't any truck guys around here, everyone has mustangs and it sucks.
