I have a knock retard at 3800-5800 special right after a transmission shift.

I tried and set PE delay to zero and decreased ETC vs PE vs RPM from 90 to 70. It lowered the knock but still there upto 4-5 deg knock.

Here a log and tune file. Any help is appreciated. Mods are in signature.

It was tune on dyno and there was no knock even when it was test driven on street by the tuner. It is later that I started to notice knock.

Thanks
