But, does it matter? Would 92 affect the timing enough to make the fuse pull worthwhile? How high should I go without a tune and does that make a difference about pulling the fuses?
Is that 100 octane gas available at the pump or is it an additive? How much do they charge for that? Very interested to hear how your car performs with that in the tank..
