If you could make more power with more boost, then you cant call it an aggressive tune

13 whp at redline is nothing to sneeze at.

Also, if you really look at the data you'll notice that the boost is actually lower with the Cosi manifold and it was also richer and still making more power.

the manifold also "unoptimized" your setup. Before you were peaking at 6200rpm which allowed you to stay in the meat of the powerband by shifting at redline.....where as now you are leaving power on the table unless you're gonna rev to 8000rpm.

I'd really like to see how far that slope carries out. almost looks like the hp peak would be 7000-7200 rpm now.

Seems like this is a mod where you're gonna need a huge turbo that causes the intake manifold to become the restriction, but once you get rid of that restriction you're gonna need a valvetrain to take advantage of your newfound powerband.
