I'd bet that it works if you are using shitty gas. If you are getting good gas, I'd imagine there isn't much difference. In other words, not enough gain to warrant a purchase. Can it flow 255lph?

I'm not sure. The marina that I keep my boat at just got rid of some bad gas that they recieved too. I used to get it from the same place was doing ok, but they shut down and now I can't seem to find anywhere that will keep my mpg consistent. Must be a bigger problem then that though.
