Some shorter logs with more 100% throttle would be nice, and please post them up using Google Docs... its free and people will be more inclined to look since they dont have to risk downloading anything.
Im no expert at all:
It seems you have some knock of up to 1.4 during WOT, and the ECU is doing some things to correct it using the Fine Knock Learning. That is a low number tho, and i think you could choose to leave it alone. Dropping down to 91 octane map would do the trick, but lose several HP and TQ. You could find higher quality gas or some quality octane booster to just barely up the fuel quality and id assume it would get rid of the small problems while staying on the 93 map.
18.8PSI at some spikes seems a little high to me... i dunno.
