I have them in my log... What difference does it make if thoes are the ONLY items logged?

I just had a thought... at 25% throttle doesn't the ECU switch to open loop? Maybe we are all fine in closed loop, but as soon as we go open loop it leans out and knocks? Too much boost at part throttle for the fuel maps in the ECU?
