You are joking aren't you? Peter has provided a heap of technical information for members on this site, just look back through all the topics, Peter has made many valuable contributions. I can't comment on your question but I know it's been said before that the auto reinforcing will be revealed when the testing and pricing has been concluded. As for the self promotion, APS is more than entitled to do so, after all APS is a sponsor of this site and consequently pay the sponsorship fees. Unlike other tuning companys. And no I don't have any APS products, but I'm greatful that Peter can share his expertise with us, whether we buy APS or not.
