I have the FI resonated HFCs on stock nismo and no rasp at all.

One thought (sorry if it's been covered) but is it possible you have a leak? Most likely at the manifold/hfc joint.

I would HIGHLY recommend the Z1 gaskets. REALLY quality metal gasket that all but eliminates any chance of leak, and cheap.
