Ltg Camaro Knock Retard Issues

Hey guys so im very new to gm stuff have tuned multiple focus st and a couple focus rs. Im having a few problems Even before Tuning My camaro is getting knock retard There is a log attached of it stock, Now this knock is not audible to me, So i start tuning it anyways and the knock doesnt seem to get any worse per say but it does become audible sounds like marbles in the damn enging when i here it. anyways there a log of 1st through 4th attached of it tuned ill also include both my tuned file and stock file im having a hell of a time guys and im sure im not doing everything i sould be if anyone can help look through my tunes or just has an idea of what i can do that would be great Attachment 108165Attachment 108166Attachment 108167Attachment 108169

Also not the only issues im having also getting throttle cut like crazy too most times i have a log of that to but for now just really trying to get the kr sorted as i just put the car back to stock because i cant have it audibly knocking. I run on 91 octane and have tried boostane it helped but doesnt remove the kr completely, i have also tried every single brand of fuel i can get here in my town.
