I' ve got a tillman 91 street/race tune for colorado. because of the move I'm pretty broke do I need a 93 tune because of the high octane there or will my car be OK untill I get the 93 tune.
Agree with GAP you don't need a new tune to run a higher octane gas.

Well, I just talk to Chris at tillman and he said that I will be ok running a 91 tune on 93 octane, just not a 93 tune on 91 octane. But like I said earlier I'll be getting a new tune as soon as I can. (waiting for the another sale at Tillman!!! )
Thanks Steve! Careful down there, them boys are a hair trigger!

Correct, we have 87, 91, and 93 available. You can run a higher octane than a vehicle (or a tune) is built for, but not a lower.
You do not want your timing to get ahead of combustion or you can damage your engine.
