Hi, let me start off by saying I live in NY, as of right now its hard to get gas because of hurricane sandy. Lines are huge and now there is no 93 octane to be found. If your ucky you can get 87 octane. But I am able to get my hands on 100oct,103, and 109. Could I run a mixure of 87 and one of those three while this is happening? Or just stay off boost and let the Ecu retard the timing on its own?

Car is mostly stock with bolts on, had a flash before.
Thanks Jerry

 

Yes you can mix. Before I switched to e85 I ran a 93/109 mix since race gas was half the distance from my old place as the e85 was.

 

Did you run it without a tune? And how much gallons each did you put in?

 

I tuned for it and had it mixed to be approx. 100 octane.
