what if i had a motor tuned to run off c16 at high boost but still wanted to maintain daily driveability at low boost and just run regular 91 octane (california, it sucks). How would i purge the fuel system to dump in a couple gallons of race gas on race day? Like maybe wire up the pump to a battery and a switch and put a gas container at the line before the fuel filter and then pour in a couple gallons? Has anyone had experience with this?

just poor in the couple gallons c16 yourself.......

Do you mean empty out some of the gas thats in their so you won't get such a diluted mix?

If thats the case, just use the return line AFTER THE FPR and poor it into another container for use later on, start up the car and let it idle. thats how we got rid of some bad gas outta a friends car.
