HPF stage 2 meth problem

FYI : from my experience the Aem picks up knock before the siren goes off and pulls timing. So u can have knock without the siren going off. I've done many logs showing the knock retard with no siren going off.and the Aem not even recording them... I adjusted the tune via knock retard as a guide & not knock volts as they happen to fast for the logs to pick up even at 250 samples a second. I now have my AEM serial gauge programmed to monitor knock retard and gives me a visible warning... Way more accurate than the siren and I don't have to worry about hearing it. I bet there r cars out there getting knock and not even knowing it.... It shows up on the Dyno graphs really well u can see the drop where knock occurs and I confirm it with the log.. This way of tuning was how I got such high torque numbers.
