How do some of you think his gains are tied to the tune when you have to retune. The car was knocking, not because of his parts , but because more air equals lean equals knock. Z1 even says you MUST retune with their manifold. If you don't like the guy that's fine , but at least he's thinking outside the box here instead of following the herd. These cars have been out for 6 years now and how often does someone try something new let alone dyno it and fess up when the gains aren't as good as he thought. Let him try with test pipes and a proper tune.
