Throwing overboost codes on top end on most WOT pulls

Just wondering if we could tweak a few more things to add some more power. Also I ended up getting 2 super knock codes one on cylinder 1 and cylinder 3. No cel popped up while I was driving though. I don’t know if it’s cause of fueling but if it’s possible could you take a look at the fuel trims and rail pressure please
