Audible Knock

[V7MB]

Hello, New poster here, I've been having a problem with Knock Retard on my 2007 Mazdaspeed 3, hopefully can get some insite into the issue, I have attached the most recent Data Log, car currently has a moderate tune on it nothing too crazy for high boost also has Cobb Intake, CP-E catless downpipe, Cobb Catback and all around Damond engine mounts, around 4k-5k RPM it starts getting a Audible Knock, i have changed Coils and plugs havent gotten to the injectors yet, the issue is pretty consistent everytime i drive it, but only happens while in boost, if i stay out of boost there is no knock, Any insite will be helpful, Thank you all!!
