well, its official. i filles up, half tank if race fuel and it does smell great!!! I LOVE IT!!!!!!!!!!!!!! but, it does nothing else.
its still worth the money though...chicks like race gas too!

 

it will leave a white residue inside your pipe....here in texas it is illegal to run race fuel on the streets, so if it is there too, then carry a rag so you can wipe it off of the inside of the exhaust tube at the end of the can.....but hell they will never get that close to see if you know what i mean...

 

I will say I was at the drap strip 2 weeks ago and I ran the first 3 runs on 93 pump gas and was running low so I put in 2 gall of race gas from the track and I did not see any time change I loved the smell of it but as for performance nothing.
