Take your oxygen sensors out or they will be expensive paperweights

Default You will need a chip that has enough adv timing to burn that 115 octane
if you run on a street chip your going to feel less power then with pump gas since the spark will be too late.

Default not a question of need... sometimes all the track has is 108 or 115 leaded
I if can use that fuel and gain power with some minor mods why not... I just dont know what it would do to internals and seals and what not.
