BPV leak would potentially cause the timing wierdness. It's really tough to pin down, since you can make boost and the leak goes back to the intake, so it doesn't really show in AFR either, it just makes the turbo work harder and since we don't have IATs in the manifold, you're a little blind to it. Wouldn't cause hesitation though unless it was a constant small leak... which a BPV leak usually is not.
+2 for checking tip in
