Its a grove that goes behind the blade of tb..has anybody heard of it or done it or has it??
Claims on mpg seem insane ..but I would be happy with my lightning at 20 mpg

Thought it was only for normally aspirated gasoline engines, so wouldn't work with your lightning. Never heard of anyone doing it.
