I suppose all the Dyno results & test equipment I use are all wrong then, there was no guess work testing the fuel mod it does work, I can prove 100% the fuel mod does adjust the A/F ratio & the mod has been tested on Dyno's by many other riders from different countries around the world. It is a very basic fuel mod & has been around for years & I have always disclosed this, to say the mod is an empty coke tin is unfounded.

I forgot to add out of the hundreds of fuel mods that I have sold over the past 7 years + the ones that members have made for them selves, in all this time I have only ever given one person back his money & that was only a month or two back.
