So my recent data logs are showing consistent knock on every pull (around 6300 rmp), and im hoping someone who knows what they are doing could check out my logs. I am running the Cobb 93 stage 3 map(with the aem intake corrections in map). I have the cobb 3port ebcs, aem intake, HKS BOV, ams widemouth downpipe, Cobb High Flow cat, and straight 3" from cat back. I am also experiencing shutter when cruising.. Any time i accelerate and let off throttle the entire car shutters a bit. I dont seem to notice it while accelerating hard or at high rpms. It is worst between 3000 - 4000 rpm. My real concern is definitely the constant knock though. I have attached 4 3rd gear pulls to redline. All logs are trimmed to make it easier to read and include AFR. Any help really would be greatly appreciated.. Thanks
