That was directed towards racecars comment about having lower octane gas in it.

I thought octane additives only boosted octane by like .8? The highest octane I can buy at the gas stations is 93, so I can't even mix higher octane fuel in it. Local track has 103, but is closed for construction

If you can find some Torco Accelerator additive, it will increase it by enough to see if that is a problem.

Thought I would update. After trying higher octane gas, and reducing timing the knock retard would not go away. Got a lt4 module that I put in when I got home from work today. Took it out and data logged it and have no more knock. Thanks everyone for the help!
