Has anyone tried the boyesen power x wing on a fuel injected bike? Was reading about them and they say crisper response, more power you know the deal. Is this more snake oil designed to lighten my wallet or is this thing worth it?

 

never heard of it before your post. Like most that stuff I feel it just smoke and mirrors.
Did a Net Search and two Moto Mags Had the same exact article, so I believe they just printed a Press Release. $129.00? for three little pieces of metal tacked together I don't think so.
