I think you're a little confused. I never bashed the PI units. In fact, I even stated I'm using one as we speak, just I'm having to have it pulled and rebuilt cause the clutch material is crap, and its slipping now. Nothing is wrong with the PI converters that I can see other than they use bad linings. Again, once they they start using high carbon friction linings, they'll be fine. As for me "liking" Edge, I didn't say I "like" their units, I'm just defending them cause I'm tired of hearing people who have no experience with the product personally turn around, and bash it like they've been screwed by the company.
It's kind of like how some people bash Mac performance for their throttle bodies, yet they've never owned a Mac performance throttle body. Sure, I bash Mac performance every now and then, but only because I have OWNED one of their throttle bodies, it was crap, and Macs customer service was of no help with the issue.
Now, with all of that having been said, the report from Auto02 leads one to believe he had a bad experience with one of Alans converters. Now, does that mean "everyone" who buys a tc from Alan will have the same results ? Nope. Again, Auto02 is just sharing his/her own personal results and experience.
