Hello everyone, I have recently done a 2015 5.3 swap and sometimes it sounds like I am getting some spark knock around 3000 rpms. I hooked up the scanner today and it did show some spark retard and one point. I have been running premium gas and the tune is basically stock, all I have done is play around with the power enrichment some. you can see the knock at around the 7 min mark. What do you guys think it could be, thanks
