    Help with timing corrections in my data logs?

    Hello, I recently had an Aquamist HFS-3 meth kit installed and has a ATP Pro Tune. My car feels to be running strong. But the data logs show some issues. Ive been having a bit of timing corrections and not too sure whats going on. I dont want to ruin the engine. Any input on these data logs would be greatly appreciated. In in datalog8 there was a yellow half engine light that came on which had a P3OFF boost leak code.

    need to post a jpg for us.

    were you over or under boost?
    boost leak will certainly have an effect on what your seeing

    Datalog 8 was the one with the boost leak, and only hit 10-11 PSI. But the timing corrections were not bad at all. Datalog6 had full boost but had timing corrections in every cylinder. Just seems like something is not right. And let me try to repost these logs. I hope you can give me some insight. Thank you for your help

    Guys just prefer to work with jpg's of the graph, not text.

    For me, text is easier as it can easily be graphed or imported into excel since its CSV.

    I see your point. I will say most guys prefer the jpg's just out of laziness as they won't take the time to do that.

    datalog 6 looks like a bit too aggressive, meth not flowing entirely??!! IATs still rise at the end.

    log 8 boost leak, probably popped a hose

    Thats what I think the issue is, the meth doesnt flow at high boost and high rpms. Not sure why. But Ive been in contact with Richard from Aquamist trying to figure it out. And yes I got a boost leak in the other pull. Its happens every once in a while.
