I have some questions that im sure some of you should be able to answer for me.
I am always reading about pump gas 91 -92 - 93.
My questions are these:
what is considered hi octane fuel?
the reason is I want to get a tune from torrie and want to make sure we have similar octane.
IM not sure if the octane ratings are universal
Here in Australia we have
91, standard fuel
95 which has 10% ethanol
98 premium unleaded (what I use)
100 with is 15 % ethanol
and now we have 107 which is e85 fuel 85 % ethanol
I think that is right.
so im just want to make sure I get the right tune done. im trying to avoid a dyno tune due to no one here know these engines
thanks in advance

Hey Damo, give me a shout. I can get you where you need to be. Sounds like our octanes are the same. You need to figure out what you plan on using to decide on tune. E85 is out unless you upgrade injectors and fuel pump to match needed fuel delivery of E85. The other fuels you'll be fine with.
