well it time to drive from sacto to fort bragg with the porsche club ... am looking for 100 oct fuel at the pump between sac and fort bragg seeems to be a very dry area only fuel i can find is at sonoma race track and thatd on the way back:to

 

why?

 

Is the car tuned to take advantage of 100?

 

why? to put in car and go fast , really have a program that calls for 100 oct and am not fond of turning it off

 

yes it"s on a program for 100 oct can reprogram for 91 but enjoy the extra hp

 

You must be driving a turbo?
