I only post what I have done and when I suffer from the miss fire all I did to my car is swap the head and no more miss fire everything else remained the same we also done plenty of 6bolt swaps and 2gs and none of them till this day suffer from that miss fire and none of them are using dsm link or aem just a afc if at that we have done one that wanted to keep his 2g head because he had work done to it and for some reason that one had the miss fire huh that's a coincident also swap the head on his car and no more miss fire that is weird huh but I don't know it just seems to me everyone running the 2g head on the 1g bottom has this miss fire like Aaron's he had the 2g head and 1g bottom and he suffered from this miss fire now his new one we installed with a complete 1g top and bottom does not suffer from this huh again a coincident huh. Like I said I only post it because I have tried it I don't post things I have not tried and that is plenty of reason for me to post it I don't post theory that I have not tried personally
