Anyone have a good timing table that won?t knock itself to death on 87 octane? I have my 15 Silverado tuned. In logs it shows a good bit of knock on 87 but it?s not audible. With 93 it shows no knock. I haven?t adjusted timing tables very much. Just 3-4 degrees and no luck . Fueling is Dialed in to within 3% with a wideband. Appreciate the help as always
