How do tuners determine what level of knock sensitivity to reduce to from stock? Specifically for HP tuners, there are a few tables related to this and my mail-order tune has the sensitivity reduced from stock however I'de like to know what guidelines you guys follow to determine what's safe.

Thanks

I'm all ears as I have an issue with one of mine and have been asking questions that no one can answer here. I have been getting more info on the Corvette forums.

If it's a for-sure false knock, I put in a safe timing map (usually the 2002 C5 Zo6) and guess and check until the "knock" doesn't occur anymore. If it has to be reduced a ton, then there's something else going on. I had a lot of tip-in burst knock on my last car that I had to get rid of too. Turns out I had a primary tube hitting the frame.

I scanned my friend's bone stock 2003 z06 and on premium he had knock retard (not burst knock) after 4000 rpm so that's surprising too. My stock 99 sierra on regular fuel on a stock tune also shows knock (not burst knock retard).
