So if you wanted to go to the track, you could fill up the day before and reprogram (add timing) for some better fuel; for example VP100(aka streetblaze 100). 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
