I'm sorry that I have to be so critical of your setup, but I fail to see the goal still...
You have a greddy intake manifold on a T25, and now you want cams..
The problem I see is this.. Your moving your powerband into a place where your turbo can no longer breathe and loses boost (high rpm). The more you move it up there, the worse off you will be. I really think the extra kick you got was almost produced by lag (with the football), because you went from 10-20ftlbs less torque at the same RPM, and then ramped up to maybe a 5hp gain for the last 1500 rpm or something, and the difference was greater than before when it was a steady curve.
I just see it as you hurting youself and making yourself slower. I could maybe understand if in the future you were to get an upgraded turbine, but why didnt you save and do the turbine first? and then the other powerband altering mods later.
Just my $.02
