    Cam Tuning Help please with a 5.3L 383 Stroker

    I have installed a new Comp Cams cam in my 5.3L 383 stroker. After the install, my ECM doesn't seem to like the new cam. I am getting the following new DTC's after the install. The cam specs are 620/610 113+2. I have attached the latest scan log, and config file used to scan with.

    Thank you for your help.

    Your in the wrong section, being an 09 you would be a gen4 motor. You have WAY to much timing pretty much everywhere. Go back to the stock tune and start over I would suggest.

    Thank you for the suggestion, however I am only seeing little knock retard due to timing. And if I see any knock, it's usually due to where I purchased the gas from.
