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.1485314854
