    knock retard?

    Hey guys, I am still wrapping my head around this so don't flame me too bad. I am just doing some learning on my 07 Tahoe 5.3 and I have a question about KR. Its the same with the stock tune but I can hit 10deg of KR in a full throttle run, I would think that would be excessive in stock trim? I got rid of burst knock and I'm still seeing it. This thing is kind of a dog so I was just curious. Thanks!

    What kind of fuel?

    I see it all the time where 87 octane just knocks forever.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
