I think they are stupid items ... any of you tried it?
or how he felt like that?

haven't tried but did do alot of reading on them his feedback is rubbish and claims the resistors and them sort of things don't work I have tested them sort of things and some of them do work and the claims are roughly right and some of them don't I used one a couple years ago that connect to the iat and gave 9.5 mpg extra 0-60 was 1.5 seconds faster

Hi, I think the first kit listed is a variant of the other two, but optimsed for use with oxyhydrogen injection (Browns Gas). I read up on this a while ago at http://www.water4gas.com. Having said that, I haven't yet tried them.

The "+20BHP power chip" guff that sells on ebay is simply a resistor placed across the MAF to trick the ecu into thinking the car is taking in more air than it actually is. The ECU compensates by overfuelling, causing a small increase in power, a big drop in fuel economy, and vastly increased wear on the engine as the bores are washed with raw petrol.

I'm sure the 'fuel saver' one works in a similar way to cause the ECU to under fuel, whch I'd imagine would result in a dog-slow car that's probably also prone to pinging and stalling.

HHO is an absolute farce, the worst sort of pseudo-science. The amount of hydrogen generated by water electrolysis at the sort of currents generated by a car alternator is miniscule. To generate enough hydrogen to run a car you'd need a transformer the size of your car putting several thousand amps through the water (the alternator in your car will put out maybe 100 amps, and you've got to run all the other electrics off that too). If it was an even remotely viable technology, we'd see manufacturers lining up to show off their 500mpg water-powered cars.
