It sounds about right. Good head flow will actually show lower boost levels...but that's a good thing. It just means that it's more efficient. Timing adjustments or even a 3.2 might really bring things to life.

I'm working on a set of heads for mine, I run a 3.2 on it now with about 10lbs of boost, and no KR. Can't wait to see what she does with heads and a 3.0.....or maybe a new engine all together!
