HELP?? FAST!!!

[Boodrodon Dykes]

Ok I just got my Xcal2. WOOHOO! k, so it has a tune on it for 91+ octane. I want to hook it up now, but I have a quater of a tank of unleaded gas. Would it be alright to still run it if I put the program on now? Or do I need to run the unleaded out first. Thanks in advanced.

pretty sure you can use that gas for the start. But I would go fill up with 91

I would use it all, just go for a cruise, then go fill up with 91. Don't want to chance detonation. Could also fill up the rest with 91 and throw in a can of octane booster if you have it. That's what I always do when I switch from 87-91 (though I just run 91 all the time now).

Can you get 93 by you???



Could also go fill up now with 91, and throw in a can of octain boost...
