Has anyone tried this stuff.
Its supposed to give around 20bhp extra per tin.
You can feel it work, Good for chil out blast.
its £20 per bottle has anyone found a better rate poss bulk buy

 

I've tried the Nos street legal, and the Nos non street legal octane booster's.

I can feel the illigal one for deffo.
I used to know a bloke who sold me octane boost in crates, now i cant find anyone since he sold up.
How dangerous is it to run an import without octane boost? (engine wise)

Thanks.
