HAHAHA u believe what a video shows u LOL. News for you, not everything u see is real, especially when the vid comes from the company that sells the product lol. If this was a race of 2 people, 1 person who purchased it and a stock one then maybe i would believe it. Yes the Nos proly does work, but for 8 seconds of power come on, u can get a awesome engine for 200 or less that will give u hours upon hours of use.
