That video didn't sound like anything I'd get too worried about, you should hear a serious case of timing rattle.
It sounded more like it hadn't warmed up completely yet.....?
Anyway, at that RPM, your timing curve is usually set to advance pretty quickly past 1/4 throttle, as well as the FRP.
Above 2K, especially 2500+ is where most tuners get more aggressive on timing.
Mind you, without the timing, EGT would get hotter and you'd make less power...
If the issue is usually worst during warmup, Rob can adjust the coolant temp based timing compensation to lessen the advance.
