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?

Be careful...the 95 or 98 isn't the octane rating. Octane is RON + MON / 2. I can't remember whether the 95/98 is RON or MON, but I went through this when I lived in the UK with my Mustang. Don't quote me, but I think when I finally found the formular the 95 was 89 octane and the 98 was 91 octane ...

Ban the f**kwit!
