Cams without a tune can be risky. The timing advance is already aggressive on the 05+ n/a and cams will typically make the problem worse as far as knock goes. I would bet the advance multiplier is far from being fully used and that means the ecu is constantly trying to advance timing, it sees knock and retards it. Wash, repeat.

The power surge at 3k could be your CL/OL delay transition, timing related or just the way the cams affect the tq curve. Or a combination.
