Default Closed Loop Knock

I have a new 2011 ms3 and I have installed the cs sri/tip and tuned with an ap. Everything in my tune looks great for WOT but while I'm just driving it around town, i get a lot of KR. It usually doesnt go much over .7 but I get it everytime i accelerate normally. I guess my question is, it this normall and safe or is there something i need to change? I get quality gas from BP. Im just using the OTS stage 1 cs sri/tip for 93 octane.
I am new to tuning but ive tried to research as much as i can in the last few months before I installed anything. Thanks for any help you can give.

Shit, I get closed loop/part throttle KR of up to 7.0 while driving around. I don't like to see it but nothing seems to change it.

Don't worry about it man. It's just the ECU trying to make the car more efficient.

I don't know, I usually don't get any KR while driving around town, only 0.7-0.50 sometimes at max load.
