    Seeing knock in my 2017 Silverado L83 A6 - First time tuner

    Trying to get a handle on this truck, ive been messing with tune and I was hearing a pinging noise during an uphill drive at constant speed. Not sure if its low octane related I run 87 in my truck. Attached is my Log and Tune File, truck has CAI, catback and transmission thermostat delete.

    Knock I was searching for begins at 4:00.000.

    Any tips or tricks would be helpful!

    Thanks

    We tell people looking for 87 tunes on Gen 5 DI truck engines that it really isn't worth it other than transmission improvements. There are gains but some trucks just require some neutering to keep them from knocking badly.

    The factory tune really needs timing pulled in a few places to be knock free on 87.
