It seems a few of the new Guzzi's ping. Not all of them, or even it seems most of them, but a few of them. Mine is one that does but mine does not ping that bad and with the ECU/AutoTune hopefully it won't anymore. I don't know if it is a tolerance issue or a setup issue (mine when new and under warranty spent a bit of time at the dealership with them unable to figure it out) or even a riding style issue but there is something that cause a few of them to ping. Funny, the older V11's had the same problem, a few of them pinged and most did not. My wifes V11 pinged until we corrected the fueling and tightened up the squish. I assume it is just one of the "undocumented features" of owning a hand built Moto Guzzi.
