built for E85 can i switch back to 93?
if i get the fuel system made to run E85 and get it tuned for E85 and sometime down the road want to go back to 93 octane would i have to change anything besides the tune? maybe smaller injectors?
i just dont wanna pull the trigger on E85 fuel system and end up not using E85 6 months later or something, if that happens
