Not sure if its the right place to put this and title is a little funny but what i want to do is drive my car to the TURBO BUICK NATIONALS its about a 4 hour ride from my house, My car currently has a 100 octane chip in it and running about 25psi boost,i mix 110 and 93 octane to get my 100 but i just drive around town this way and local tracks but what is my best option to drive car that far and not be able to just stop and get 100 octane just anywhere? What do i need to change?
