Ive got the 91 race tune right now and its pretty good, but i want to try it with 94 octane. If i adjust the global timing up 2* would i be able to safely run a higher octane fuel? Anyone try this yet, i emailed doug a while ago to ask him but he hasn't gotten back to me yet

 

I answered your question in another thread, but no problem repeating it.
You should be fine. But if it pings, then just pull some timing.
