please help lz9 knock...

So a couple years ago I did some tuning on my 06 g6 gtp for 87. I decided to run a wet 75 shot so i pulled a couple deg of timing out of it to start. before spraying i decided to log and see what it was doing and i am getting knock its pulling anywheres from 2 deg. to 7. The part i am having trouble with is that i had no knock when i tuned for 87 pulled 2 deg. and i am running 93 but its picking up knock? I also lost my stock tune for comparison if anybody has one that would be great. Thanks for your help in advance. btw i am by no means a professional tuner.1111.efijon g6 87-2deg.tun

No help? a little more info i am confuzed on, I changed back to a factory tune and logged it still has nock. it pulled 2.7 deg at 5000 rpm but just before it pulled timming it had 28.5 degs when the spark table never goes over 24@ 5000rpm.
