Getting some occasional engine knock...opinions?

On two occasions now I've gotten some knock while at full throttle near 5000 rpm in second gear. The weather has been relatively cold each time. I'm not really all that worried about it, but just was wondering if you guys had any thoughts on it.

I just recently installed an AFPR at 15 PSI, and have noticed a decent power gain from it, I'd never had any problems before this, so I figure it is the reason. It's only happened twice, so what the hell I'm just adding some 104 octane booster and not messing with anything. What do you all think?

Cold air demands less timing then warmer air, with 52-70dF consider average temps.
