Only moderators can check the IP addresses. As CT said, these thee (MaV, uneed2know, and gsr2000) all come from different IP addresses. And MaV's IP address does indicate that it is from a .DK domain. I am quite willing to believe that these people are all different individuals.
On the other hand, I am still conviced uneed2know is lying about the dyno shops. He really got greedy there claiming an 80 mpg increase and all, not to mention making up a 430 hp Civic with a very unlikely combination of mods. If you're reading this, uneed2know, let's see you try proving this. But I suspect he's run off with his tail between his legs. He knows his credibility is ruined if he can't produce the contact information for his fictitious shops.
It is true that I have never tried the Turbonator. I have also never tried to get more horsepower by putting a lucky horseshoe in my air cleaner. When you have a part that (1) would need to defy the laws of physics to work as claimed, (2) never shows up on race cars where they spend thousands for just one more horsepower, and (3) has been dyno tested by several reputable magazines such as Sport Compact Car and found not to work, I don't really plan on trying it myself. Unless I'm planning to write a book about separating worthless cheap mods from ones that actually work, in which case I would probably get one so I could have a real dyno graph.
