went out and my first blast to 130 i had 1.67* of knock. did it again and i got no knock and then i went up in 5th gear and got no knock and the 02's were up. now my fuel trims arent zero at cruise, is that because it needs more WOT fuel? i put in about .75% more and im gonna try that out but is that normal for the first run to show knock and not the others? is that just the computer tryin to compensate? and if i adjust it it shouldnt need to compensate for anything right?

Under 2 degree's of knock is nothing to worry about.Each adjustment you do needs atleast 100 miles to settle itself in on the L-terms ect.

totally agree with that. The custom tune in my car currently got almost 5% of KR at WOT, and now it gets 0 after about 500 miles.
