Has anyone gotten their intake valves and ports cleaned under warranty?

Just curious if anyone has been able to get this done under warranty (CPO as well). I have about 57k miles on mine and as of lately I've been experiencing some surging on acceleration on the stock tune as well as rough idle here and there. I am not throwing any codes and have replaced my spark plugs about 2k miles ago.
