And ideally you don't want any KR when FI. You can get away with a few degrees, but it seems these pistons are easy to chip so ideally you should tune it all out if possible.
I only see it when I get on the throttle. At idle I don't see any at all. I just wanted to make sure and get some peace of mind. I'm not modded yet but I will when I free up some money. Haha. I'll probably end up top swapping or swapping out the motor with a lower mileage one. I'm currently at 155k I think.
