Ok, so I got my tune loaded and did a datalog with the SCT On the knock it showed it was going a little negative then up to 3 on a 3rd gear roll at about 60% throttle. asked Torrie and he told me he needs the load to figure out where to adjust it. Its not an audible knock, but it showed on the graph. I did another one today and it was going up to 5 (still dont hear anything). I'm going to log on my laptop to get more parameters but my question is when is the point where the knock gets too bad to further log it or cause damage.  :-[ New to this tuning stuff so go easy on me lol. The air/fuel ratio is fubared as Mike put it so maybe the pids are off ?

On the trucks the ecm can compensate for up to 6 max. I don't mind seeing 3ish, any more than that and I want something adjusted to bring it down.
