Not much to look at from the log but...
Load to KPA is off...
You seem to be running pig rich especially on the high rpms... (injector duty vs boost comparison)
Could be your MAF scaling is off... could be you have not tuned your afrs right... could be anything..
post a screen shot of your 3D VE table, Maf Scaling & Comp, Kpa to Load, Volts to KPA, High Oct fuel Map, Knock sensor filtering tables, together with a log that has afrs....
