The thing you really have to worry about is if you have a negative Knock Learn Value and are seeing constant Knock Correction with full throttle and under boost. That means the ECU is consistently seeing knock in that area and is trying to do the best it can to correct it. The Knock Learn Value is more like a long term knock correction where the ECU says I have seen knock here before so I will pull timing even if I don't see knock where the Knock Correction is I see knock right now I am going to pull timing.

Thanks for that info. I am going through logs trying to establish what the "normal" conditions are for the operation. Everyone I talk to with the Vortech kit all say just go out and beat on it. I am not that type of person until I know where everything is at and where it should be and why.
