Here in Michigan we can buy 94 octane fuel from Sunoco. If I were to use this fuel, how should I adjust the 93CAI tune I'll be running once the snow melts?
Can I give it a couple extra degrees of timing? What's recommended and what's safe?

Careful there.... Sunoco 94 is 10% Ethanol... do not adjust the 93CAI tune and just run it with increased shift points.
