    First Tune and Log after Headers

    Car is a 2015 M6 GT PP. Has ARH headers, catless mids, and Corsa Sport catback, otherwise 100% stock. Any thoughts on my first logs with a few WOT pulls? Seems to pull cleanly and drives like stock, feels a LITTLE lazy down low (below 4,000rpms) but hard to tell she is so goddamn loud lol.

    Installing my GT350 intake and cold air tonight, just wanted to get her running right with no codes just with the headers.

    You could probably use more timing, maybe 26 to 27 at 7,000rpm
