Then plug back in afterwards and go back to less expensive pump gas. I certainly don't know how it all works as you do rcompart(Rudy?) but is this possible? Having our own personal portable tuner with 2 custom tunes(specifically for the mods we happen to have) would be great. Just like it's great in our turbo diesel trucks. And they're very affordable; perhaps the millions of trucks out there makes this possible. Can you make one of these for all of us? kidding! Bob

I am just really pleased about a "SWITCH" in the works that will do what I was looking for and thinking about; however it works. Pump gas to race fuel and back (with a simple switch) is an awesome Mod. Can't wait to spend more money.lol Bob

If the station is on the Mo. side of the state line, then I'm almost certain it has ETOH in it...something like a 10% blend. There is no more energy in a gallon of 93 octane pure gas than there is in a gallon of 87 octane pure gas...it's just a measure of it's resistance to "knock" (i.e., explode on it's own)...
So, a gallon of 10% ETOH 93 octane fuel will only have 96.5% as much "energy" as a gallon of pure gas (even if it's an 87 octane fuel).

I work in Mo. (Lukes on the Plaza), but live in Ks. ....way out by the NASCAR track....& usually wash them in the driveway.
