does alky lower your O2's?

[turbowrenchhead]

I have alky on my hot air. My O2's are at 750mv at wot. Is this to lean or normal? I can run 17 psi of boost on 93 with a 25 degree timing chip. On 110 octane I can only run 20 psi of boost with the the alky.

On my intercooled 86 gn alcohol made me richer up to 80 miles an hour and not much difference after that.You might be a little on the lean side.Bruce
