As I've said previously (maybe it was in another thread), there is a difference between what you are probably experiencing versus what I consider "real knock". If it were real knock, you would hear it and feel it. Just the feeling real knock gives is enough to make you want to have your car checked out.
Just because it comes up as KR doesn't mean it's a big problem. However, you want to minimize the potential for that real knock as much as possible. Like previously mentioned, an e-tune or a dyno-tune is probably the best idea. These maps are generic and the car's observation equipment can only account for so much of the infinite variables that affect the way your car performs.
These off-the-shelf maps will work extremely well for about 90% of people who use them. The other 10% will work, but just not as well as you would expect.
If you are having problems with knock, I highly encourage you to move to a 91 octane map. You'll notice very minimal power loss. In fact, because the ECU isn't constantly dialing back timing mid-acceleration your car will probably feel faster.
Just because you have access to 93 octane gas does not mean you should be running a 93 octane map.
