Think of it as de-tunning your engine, complete waste of time and sh|t! If you think about how it works and visit the website on how they work you''l soon realise there is no way in HELL these fake advertising things will work....

Hell even adding dual/single different carbies and working your engine a bit may not even give you an extra 35hp!!

But if you want to just rip apart your computer and stick the processor chip and power supply fan on the intake of your efi/ air cleaner same thing and for free....

Surley these people should be taken down for false advertising!
