I just bought a drum of 104 unleaded. Is this enough octane to tune to 20 PSI at 10.8 @ 14* ?
Thanks
PS: I want to use my Innovate which the Bosch doesnt like lead.

I ran this exact same gas on at t-61 at 22psi and afr's in the high 11s. I switched to VP MS109 when I increased boost to 26psi.

You can go even leaner at that boost but make sure your advance isnt too crazy

GenIII---what power did you put down at that boost level and what turbo?
