    Tune File Depot has a .coz file for a 2009 LC9 with a 5.3 but unless you or someone there can read your ECM with the "other" software, won't help you much.

    Subtracted 6 degrees from the whole HO timing table. Increased PE Delay to 8192 RPM. What shop did that?

    Use the Russ09Avalanch53A6 file for the compare.

    Not sure what those engine codes are but your file compares with just a few differences to the Russ09Avalanch file I posted. I don't see how you can say both files are the same when one is flex fuel and one isn't.
