AC Autotechnic makes good stuff, i dont wanna hate on them, but theres a VERY slim possibility that any of their intakes can outperform a decent Injen or AEM. That dyno theory probably came from the test being done back to back to back dyno runs, with the AC being the first intake, without a chance for the engine to cool down...who knows.

The owner of Advanced Concepts (hence the AC) is a cool guy, i dont know him personally but i met him once a while back at TG Race Designs in Alhambra.
