I'll chime in to Cyril's defense here. If you'll look at the early postings on this thread I was skeptical as well, but Cyril posted a link to an article of a third-party review of the product that showed Dyno runs. Therefore I would give it a serious second look. If a manufacturer claims their product adds hp/torque, that's one thing. If they post before/after dyno runs to back up their claim then I take a closer look. If an independent 3rd party backs up those claims, then its most likely the real deal. I'll give Cyril the benefit of the doubt on this one and defer to his real-life experiences with the product. Once my warranty expires I will seriously consider getting one for myself as well.
