So about 150 miles after installing my cs midpipe onto my cs dp, and switching to stage 2 + mscai 91, I've been seeing really high knock on low loads. Between 2 and 3rd gear I keep hitting kr higher than four. Before I would hit 2 or something every once and awhile on low loads, but now its getting a little ridiculous. Is there a reason for the sudden increase in kr after I changed maps. I put 93 octane in, and the map is 91. Any ideas or advice?
