Even dyno tests can lie, but if done by unbiased individuals, can reveal quite a bit about any product (the 2006 Yamaha R6 'fib' comes to mind). But when no dyno tests are available period (I-cat could easily do several if they really wanted; if it was actually designed and engineered, there is no chance that they didn't dyno test it, which would call into question why there isn't loads of data on the unit), the product is highly suspicious. Companies have everything to gain by publishing cheap dyno charts, so if they dont... As I understand it, the product was originally pandered by Nology as mentioned by Qadsan, but scrapped long ago. Unfortunately, the electrical system on a motorcycle is nothing more than a 'black box' for most people (good mechanics included), so it's easier to believe tall tales about a device like the I-Cat than, say, spray-on Ti-Nitride coating. Here's a scenario I've actually joked about with friends. I could go out and buy spark-plug wire with a color coated jacket from China, start up a company named "Power-MX Inc.", and resell the cables at $80 a pop. Would people buy them with absolutely no more information than my sales brochure? Apparently, because that's what many people are doing with I-Cat, and $80 is far cheaper than $200. And the beauty would be that most people don't replace their corroded plug wires often enough, so everyone who tried it would notice easier starting and some residual power gains of a neglible amount (though many would 'feel a HUGE power jump by the seat of their pants'). And as a kicker, I could go track down a PH.D student at my local university, and offer a cut of the profits for him to 'certify the design' of the wire, just to motivate a few extra people to try it out. Then I could go get it tested in a 'reputable' publication like Dirt Rider; I recently read an article on an Acerbis headlight unit that actually fell apart during testing with them, but they still gave it 7/10. I call that good odds, especially when I advertise with them and give them a couple freebies. In other words, paying for an I-Cat is half way to an Edelbrock carburator, which infact does increase power AND fuel economy by a few MPG (as tested on ADVrider.com). So, might just want to go with that. Off the soapbox now.
