I got headers with catless xpipe installed last weekend and now I am getting some knock at low loads, mostly during tip in. Its not repeatable either so it doesn't happen all the time which make me believe to be burst knock. My question is do you deactivate burst knock completely or reduce the base map so its not predicting that much?
With the stock exhaust it never did this. Since the headers shift the air flow I am adding some fuel between 2700-4350 Hz, roughly ~3-4% but I don't think this would cause the knock.
